65-489: A pulse , in physiology, is the throbbing of arteries resulting from heartbeat. Pulse , The Pulse or Pulses may also refer to: Pulse Claudius Galen was perhaps the first physiologist to describe the pulse. The pulse is an expedient tactile method of determination of systolic blood pressure to a trained observer. Diastolic blood pressure is non-palpable and unobservable by tactile methods, occurring between heartbeats. Pressure waves generated by

130-427: A 50% or greater increase from baseline had been found associated with increased event rates of aortic valve stenosis related events ( cardiovascular death , hospitalization with heart failure due to progression of aortic valve stenosis, or aortic valve replacement surgery). In patients with non-severe asymptomatic aortic valve stenosis and no overt coronary artery disease , the increased troponin T (above 14 pg/mL)

195-407: A common finding after TAVI due to the close proximity of the atrioventricular conduction system to the aortic root. For infants and children, balloon valvuloplasty , where a balloon is inflated to stretch the valve and allow greater flow, may also be effective. In adults, however, it is generally ineffective, as the valve tends to return to a stenosed state. The surgeon will make a small incision at

260-516: A consequence of this stenosis, the left ventricle must generate a higher pressure with each contraction to effectively move blood forward into the aorta. Initially, the LV generates this increased pressure by thickening its muscular walls (myocardial hypertrophy). The type of hypertrophy most commonly seen in AS is known as concentric hypertrophy, in which the walls of the LV are (approximately) equally thickened. In

325-424: A definitive diagnosis, indicating severe stenosis in valve area of <1.0 cm (normally about 3 cm ). It can directly measure the pressure on both sides of the aortic valve. The pressure gradient may be used as a decision point for treatment. It is useful in symptomatic people before surgery. The standard for diagnosis of aortic stenosis is non-invasive testing with echocardiography. Cardiac catheterization

390-408: A few months. Complications such as heart failure may be treated in the same way as in those with mild to moderate AS. In those with severe disease a number of medications should be avoided, including ACE inhibitors , nitroglycerin , and some beta blockers . Nitroprusside or phenylephrine may be used in those with decompensated heart failure depending on the blood pressure. Aortic stenosis

455-417: A good and well-established longer-term prognosis. A diseased aortic valve is most commonly replaced using a surgical procedure with either a mechanical or a tissue valve. The procedure is done either in an open-heart surgical procedure or, in a smaller but growing number of cases, a minimally invasive cardiac surgery (MICS) procedure. Minimally invasive approach via right minithoracotomy is most beneficial in

520-458: A grave prognosis in people with AS. People with CHF attributable to AS have a 2-year mortality rate of 50% if the aortic valve is not replaced. CHF in the setting of AS is due to a combination of left ventricular hypertrophy with fibrosis, systolic dysfunction (a decrease in the ejection fraction ) and diastolic dysfunction (elevated filling pressure of the LV). In Heyde's syndrome , aortic stenosis

585-403: A mean age of 65 to 70 years. CAVD is the build-up of calcium on the cusps of the valve, and this calcification causes hardening and stenosis of the valve. Another major cause of aortic stenosis is the calcification of a congenital bicuspid aortic valve or, more rarely, a congenital unicuspid aortic valve. Those with unicuspid aortic valves typically need intervention when very young, often as

650-580: A newborn. While those with congenital bicuspid aortic valve make up 30-40% of those presenting during adulthood and typically presenting earlier (ages 40+ to 50+) than those with tricuspid aortic valves (65+). Acute rheumatic fever post-inflammatory is the cause of less than 10% of cases. Rare causes of aortic stenosis include Fabry disease , systemic lupus erythematosus , Paget disease , high blood uric acid levels , and infection . The human aortic valve normally consists of three cusps or leaflets and has an opening of 3.0-4.0 square centimeters. When

715-433: A normal valve may also harden over the decades due to calcification . A bicuspid aortic valve affects about one to two percent of the population. As of 2014 rheumatic heart disease mostly occurs in the developing world . Risk factors are similar to those of coronary artery disease and include smoking , high blood pressure , high cholesterol , diabetes , and being male. The aortic valve usually has three leaflets and

780-401: A noticeable delay between the first heart sound (on auscultation ) and the corresponding pulse in the carotid artery ('apical-carotid delay'). In a similar manner, there may be a delay between the appearance of each pulse in the brachial artery (in the arm) and the radial artery (in the wrist). The first heart sound may be followed by a sharp ejection sound ("ejection click") best heard at

845-580: A result of the stenosis having placed a chronically high-pressure load on the left ventricle (with LVH being the expected response to chronic pressure loads on the left ventricle no matter what the cause). As noted above, the calcification process that occurs in aortic stenosis can progress to extend beyond the aortic valve and into the electrical conduction system of the heart . Evidence of this phenomenon may rarely include ECG patterns characteristic of certain types of heart block such as Left bundle branch block . Cardiac chamber catheterization provides

910-422: A stenotic pulmonary valve, which will diminish slightly in intensity during inspiration. An easily heard systolic , crescendo-decrescendo (i.e., 'ejection') murmur is heard loudest at the upper right sternal border, at the 2nd right intercostal space , and radiates to the carotid arteries bilaterally. The murmur increases with squatting and decreases with standing and isometric muscular contraction such as

975-425: Is a result of the increasing calcification of the valve preventing it from "snapping" shut and producing a sharp, loud sound. Due to increases in left ventricular pressure from the stenotic aortic valve, over time the ventricle may hypertrophy, resulting in diastolic dysfunction. As a result, there may be a fourth heart sound due to the stiff ventricle. With continued increases in ventricular pressure, dilatation of

1040-599: Is associated with gastrointestinal bleeding due to angiodysplasia of the colon . Recent research has shown that the stenosis causes a form of von Willebrand disease by breaking down its associated coagulation factor ( factor VIII -associated antigen, also called von Willebrand factor ), due to increased turbulence around the stenotic valve. Notwithstanding the foregoing , the American Heart Association changed its recommendations regarding antibiotic prophylaxis for endocarditis . Specifically, as of 2007 it

1105-1221: Is called "intermittent pulse". Examples of regular intermittent (regularly irregular) pulse include pulsus bigeminus , second-degree atrioventricular block . An example of irregular intermittent (irregularly irregular) pulse is atrial fibrillation . The degree of expansion displayed by artery during diastolic and systolic state is called volume. It is also known as amplitude, expansion or size of pulse. A weak pulse signifies narrow pulse pressure . It may be due to low cardiac output (as seen in shock , congestive cardiac failure ), hypovolemia , valvular heart disease (such as aortic outflow tract obstruction , mitral stenosis , aortic arch syndrome ) etc. A bounding pulse signifies high pulse pressure. It may be due to low peripheral resistance (as seen in fever , anemia , thyrotoxicosis , hyperkinetic heart syndrome  [ de ] , A-V fistula , Paget's disease , beriberi , liver cirrhosis ), increased cardiac output, increased stroke volume (as seen in anxiety, exercise, complete heart block , aortic regurgitation ), decreased distensibility of arterial system (as seen in atherosclerosis , hypertension and coarctation of aorta ). The strength of

1170-431: Is coexisting aortic regurgitation). The delay can also be observed in supravalvar aortic stenosis . Several pulse patterns can be of clinical significance. These include: Sites can be divided into peripheral pulses and central pulses. Central pulses include the carotid, femoral, and brachial pulses. Although the pulse can be felt in multiple places in the head, people should not normally hear their heartbeats within

1235-707: Is located between the left ventricle of the heart, and the aorta. AS typically results in a heart murmur . Its severity can be divided into mild, moderate, severe, and very severe, distinguishable by ultrasound scan of the heart . Aortic stenosis is typically followed using repeated ultrasound scans. Once it has become severe, treatment primarily involves valve replacement surgery , with transcatheter aortic valve replacement (TAVR) being an option in some who are at high risk from surgery. Valves may either be mechanical or bioprosthetic , with each having risks and benefits. Another less invasive procedure, balloon aortic valvuloplasty (BAV), may result in benefit, but for only

1300-462: Is most often diagnosed when it is asymptomatic and can sometimes be detected during routine examination of the heart and circulatory system. Good evidence exists to demonstrate that certain characteristics of the peripheral pulse can rule in the diagnosis. In particular, there may be a slow and/or sustained upstroke of the arterial pulse, and the pulse may be of low volume. This is sometimes referred to as pulsus parvus et tardus . There may also be

1365-469: Is normally compensated for by an increase in the cardiac output. Since people with severe AS cannot increase their cardiac output, the blood pressure falls and the person will faint due to decreased blood perfusion to the brain . A second theory is that during exercise the high pressures generated in the hypertrophied left ventricle cause a vasodepressor response, which causes a secondary peripheral vasodilation that, in turn, causes decreased blood flow to

SECTION 20

1430-416: Is not replaced. It is unclear why aortic stenosis causes syncope. One theory is that severe AS produces a nearly fixed cardiac output . When a person with aortic stenosis exercises, their peripheral vascular resistance will decrease as the blood vessels of the skeletal muscles dilate to allow the muscles to receive more blood to allow them to do more work. This decrease in peripheral vascular resistance

1495-676: Is recommended that such prophylaxis should be limited only to those with prosthetic heart valves, those with previous episode(s) of endocarditis, and those with certain types of congenital heart disease. Since the stenosed aortic valve may limit the heart's output, people with aortic stenosis are at risk of syncope and dangerously low blood pressure should they use any of a number of medications for cardiovascular diseases that often coexist with aortic stenosis. Examples include nitroglycerin , nitrates , ACE inhibitors , terazosin (Hytrin), and hydralazine . Note that all of these substances lead to peripheral vasodilation . Under normal circumstances, in

1560-403: Is reserved for cases in which there is a discrepancy between the clinical picture and non-invasive testing, due to risks inherent to crossing the aortic valve, such as stroke. Echocardiogram (heart ultrasound) is the best non-invasive way to evaluate the aortic valve anatomy and function. The aortic valve area can be calculated non-invasively using echocardiographic flow velocities. Using

1625-453: Is seen in aortic regurgitation. A slow rising and slowly falling pulse (pulsus tardus) is seen in aortic stenosis. Comparing pulses and different places gives valuable clinical information. A discrepant or unequal pulse between left and right radial artery is observed in anomalous or aberrant course of artery, coarctation of aorta, aortitis , dissecting aneurysm , peripheral embolism etc. An unequal pulse between upper and lower extremities

1690-445: Is seen in coarctation to aorta, aortitis, block at bifurcation of aorta , dissection of aorta , iatrogenic trauma and arteriosclerotic obstruction. A normal artery is not palpable after flattening by digital pressure. A thick radial artery which is palpable 7.5–10 cm up the forearm is suggestive of arteriosclerosis. In coarctation of aorta, femoral pulse may be significantly delayed as compared to radial pulse (unless there

1755-464: Is strictly contraindicated in symptomatic patients with severe aortic stenosis. Exercise stress test is now recommended by current guidelines in asymptomatic patients and may provide incremental prognostic value. Eventually, however, the heart muscle will require more blood supply at rest than can be supplied by the coronary artery branches. At this point there may be signs of ventricular strain pattern (ST segment depression and T wave inversion) on

1820-459: Is the most common valvular heart disease in the developed world . It affects about 2% of people who are over 65 years of age. Estimated rates were not known in most of the developing world as of 2014. In those who have symptoms, without repair the chance of death at five years is about 50% and at 10 years is about 90%. Aortic stenosis was first described by French physician Lazare Rivière in 1663. Symptoms related to aortic stenosis depend on

1885-665: Is thought to be involved in the earlier stages of the pathogenesis of AS and its associated risk factors are known to promote the deposition of LDL cholesterol and lipoprotein(a) , a highly damaging substance, into the aortic valve, causing significant damage and stenosis over time. Infiltration of inflammatory cells (macrophages, T lymphocytes), followed by the release of inflammatory mediators such as interleukin-1-beta and transforming growth factor beta-1 occurs. Subsequently, fibroblasts differentiate into osteoblast-like cells, which results in abnormal bone matrix deposition leading to progressive valvular calcification and stenosis. As

1950-415: Is used to quantify the degree of calcification of the aortic valve. According to the 2021 ESC/EACTS Guidelines for the management of valvular heart disease the recommended thresholds indicating severe aortic stenosis are > 1200 AU in women and > 2000 AU in men. Treatment is generally not necessary in people without symptoms. In moderate cases echocardiography is performed every 1–2 years to monitor

2015-460: The EKG , suggesting subendocardial ischemia. The subendocardium is the region that is most susceptible to ischemia because it is the most distant from the epicardial coronary arteries. Syncope (fainting spells) from aortic valve stenosis is usually exertional. In the setting of heart failure it increases the risk of death. In people with syncope, the three-year mortality rate is 50% if the aortic valve

2080-478: The Valsalva maneuver , which helps distinguish it from hypertrophic obstructive cardiomyopathy (HOCM). The murmur is louder during expiration but is also easily heard during inspiration. The more severe the degree of the stenosis, the later the peak occurs in the crescendo-decrescendo of the murmur. The second heart sound ( A 2 ) tends to become decreased and softer as the aortic stenosis becomes more severe. This

2145-426: The lower left sternal border and the apex, and, thus, appear to be "split". The ejection sound, caused by the impact of left ventricular outflow against the partially fused aortic valve leaflets, is more commonly associated with a mobile bicuspid aortic valve than an immobile calcified aortic valve. The intensity of this sound does not vary with respiration, which helps distinguish it from the ejection click produced by

2210-447: The myocardium (see "Angina" below), abnormal heart rhythms may develop. These can lead to syncope. Finally, in calcific aortic stenosis at least, the calcification in and around the aortic valve can progress and extend to involve the electrical conduction system of the heart . If that occurs, the result may be heart block , a potentially lethal condition of which syncope may be a symptom. Congestive heart failure (CHF) carries

2275-400: The 1970s. The pulse may be further indirectly observed under light absorbances of varying wavelengths with assigned and inexpensively reproduced mathematical ratios. Applied capture of variances of light signal from the blood component hemoglobin under oxygenated vs. deoxygenated conditions allows the technology of pulse oximetry . The rate of the pulse can be observed and measured on

2340-479: The absence of aortic stenosis, the heart is able to increase its output and thereby offset the effect of the dilated blood vessels. In some cases of aortic stenosis, however, due to the obstruction of blood flow out of the heart caused by the stenosed aortic valve, cardiac output cannot be increased. Low blood pressure or syncope may ensue. Aortic stenosis is most commonly caused by age-related progressive calcific aortic valve disease (CAVD) (>50% of cases), with

2405-441: The brain resulting in loss of consciousness. Indeed, in aortic stenosis, because of the fixed obstruction to blood flow out from the heart, it may be impossible for the heart to increase its output to offset peripheral vasodilation. A third mechanism may sometimes be operative. Due to the hypertrophy of the left ventricle in aortic stenosis, including the consequent inability of the coronary arteries to adequately supply blood to

2470-415: The characteristic " Dresden china " appearance of pallor with a light flush . Angina in setting of heart failure also increases the risk of death. In people with angina, the 5-year mortality rate is 50% if the aortic valve is not replaced. Angina in the setting of AS occurs due to left ventricular hypertrophy (LVH) that is caused by the constant production of increased pressure required to overcome

2535-559: The degree of stenosis. Most people with mild to moderate aortic stenosis do not have symptoms. Symptoms usually present in individuals with severe aortic stenosis, though they may also occur in those with mild to moderate aortic stenosis. The three main symptoms of aortic stenosis are loss of consciousness , anginal chest pain and shortness of breath with activity or other symptoms of heart failure such as shortness of breath while lying flat , episodes of shortness of breath at night , or swollen legs and feet . It may also be accompanied by

2600-407: The diagnosis and provide clues as to the severity of the disease, showing the degree of calcification of the valve, and in a chronic condition, an enlarged left ventricle and atrium. The use of CT calcium scoring is gaining spread as a diagnostic tool to complement echo in the assessment of patients with aortic stenosis. Aortic valve calcium scoring by multidetector computed tomography (CT-AVC)

2665-402: The disease occurs as a result of active cellular processes, suggesting that targeting these processes may lead to viable therapeutic approaches. Observational studies demonstrated an association between lowered cholesterol with statins and decreased progression, but a randomized clinical trial published in 2005 failed to find any effect on calcific aortic stenosis. The effect of statins on

2730-399: The exit of the left ventricle of the heart (where the aorta begins), such that problems result. It may occur at the aortic valve as well as above and below this level. It typically gets worse over time. Symptoms often come on gradually with a decreased ability to exercise often occurring first. If heart failure , loss of consciousness , or heart related chest pain occur due to AS

2795-446: The head. This is called pulsatile tinnitus , and it can indicate several medical disorders. Pulse rate was first measured by ancient Greek physicians and scientists. The first person to measure the heart beat was Herophilus of Alexandria , Egypt (c. 335–280 BC) who designed a water clock to time the pulse. Rumi has mentioned in a poem that "The wise physician measured the patient's pulse and became aware of his condition." It shows

2860-468: The heart in systole move the arterial walls. Forward movement of blood occurs when the boundaries are pliable and compliant. These properties form enough to create a palpable pressure wave. Pulse velocity, pulse deficits and much more physiologic data are readily and simplistically visualized by the use of one or more arterial catheters connected to a transducer and oscilloscope . This invasive technique has been commonly used in intensive care since

2925-487: The high risk patient such as the elderly, the obese, those with chronic obstructive pulmonary, chronic kidney disease and those requiring re-operative surgery. Globally more than 250,000 people have received transcatheter aortic valve intervention (TAVI). For people who are not candidates for surgical valve replacement and most patients who are older than 75, TAVI may be a suitable alternative. Conduction abnormalities requiring permanent pacemaker (PPM) implantation remain

2990-454: The later stages, the left ventricle dilates, the wall thins, and the systolic function deteriorates (resulting in impaired ability to pump blood forward). Morris and Innasimuthu et al. showed that different coronary anatomy is associated with different valve diseases. Research was in progress in 2010 to see if different coronary anatomy might lead to turbulent flow at the level of valves leading to inflammation and degeneration. Aortic stenosis

3055-575: The left ventricle contracts, it forces blood through the valve into the aorta and subsequently to the rest of the body. When the left ventricle expands again, the aortic valve closes and prevents the blood in the aorta from flowing backward ( regurgitation ) into the left ventricle. In aortic stenosis, the opening of the aortic valve becomes narrowed or constricted ( stenotic ) (e.g., due to calcification). Degenerative (the most common variety), and bicuspid aortic stenosis both begin with damage to endothelial cells from increased mechanical stress. Inflammation

3120-404: The most effective treatment for this disease process and is currently recommended for patients after the onset of symptoms, as of 2016 aortic valve replacement approaches included open-heart surgery, minimally invasive cardiac surgery (MICS), and minimally invasive catheter-based (percutaneous) aortic valve replacement. However, surgical aortic valve replacement is well-studied, and generally has

3185-403: The outcomes are worse. Loss of consciousness typically occurs with standing or exercising. Signs of heart failure include shortness of breath especially when lying down , at night , or with exercise, and swelling of the legs . Thickening of the valve without causing obstruction is known as aortic sclerosis . Causes include being born with a bicuspid aortic valve , and rheumatic fever ;

3250-434: The outside of an artery by tactile or visual means. It is recorded as arterial beats per minute or BPM. Although the pulse and heart beat are related, they are not the same. For example, there is a delay between the onset of the heart beat and the onset of the pulse, known as the pulse transit time , which varies by site. Similarly measurements of heart rate variability and pulse rate variability differ. In healthy people,

3315-461: The periphery, meaning the pulse rate is lower than the heart rate. Pulse deficit has been found to be significant in the context of premature ventricular contraction and atrial fibrillation . A normal pulse is regular in rhythm and force. An irregular pulse may be due to sinus arrhythmia , ectopic beats , atrial fibrillation , paroxysmal atrial tachycardia , atrial flutter , partial heart block etc. Intermittent dropping out of beats at pulse

3380-416: The practice was common during Rumi's era and geography. The first person to accurately measure the pulse rate was Santorio Santorii who invented the pulsilogium , a form of pendulum which was later studied by Galileo Galilei . A century later another physician, de Lacroix , used the pulsilogium to test cardiac function. Aortic stenosis Aortic stenosis ( AS or AoS ) is the narrowing of

3445-417: The presence of mitral stenosis , heart failure , co-existent aortic regurgitation and also ischaemic heart disease (disease related to the decreased blood supply and oxygen causing ischemia). Echocardiogram may also show left ventricular hypertrophy, thickened and immobile aortic valve, and dilated aortic root. However, it may appear deceptively normal in acute cases. A chest X-ray can also assist in

3510-423: The presence of simultaneous aortic stenosis and insufficiency, e.g., pulsus bisferiens , emerge. According to a meta-analysis , the most useful findings for ruling in aortic stenosis in the clinical setting were slow rate of rise of the carotid pulse (positive likelihood ratio ranged 2.8–130 across studies), mid to late peak intensity of the murmur (positive likelihood ratio, 8.0–101), and decreased intensity of

3575-522: The pressure gradient caused by the AS. While the muscular layer of the left ventricle thickens, the arteries that supply the muscle do not get significantly longer or bigger, so the muscle may not receive enough blood supply to meet its oxygen requirement. This ischemia may first be evident during exercise when the heart muscle requires increased blood supply to compensate for the increased workload. The individual may complain of anginal chest pain with exertion. Exercise stress testing with or without imaging

3640-518: The progression of AS is unclear. A 2007 study found a slowing of aortic stenosis with rosuvastatin . In 2013 it was reported that trials did not show any benefit in slowing AS progression, but did demonstrate a decrease in ischemic cardiovascular events. In general, medical therapy has relatively poor efficacy in treating aortic stenosis. However, it may be useful to manage commonly coexisting conditions that correlate with aortic stenosis: Aortic valve repair or aortic valve reconstruction describes

3705-423: The progression, possibly complemented with a cardiac stress test . In severe cases, echocardiography is performed every 3–6 months. In both moderate and mild cases, the person should immediately make a revisit or be admitted for inpatient care if any new related symptoms appear. There are no therapeutic options currently available to treat people with aortic valve stenosis; however, studies in 2014 indicated that

3770-474: The pulse can also be reported: Also known as compressibility of pulse. It is a rough measure of systolic blood pressure . It corresponds to diastolic blood pressure . A low tension pulse (pulsus mollis), the vessel is soft or impalpable between beats. In high tension pulse (pulsus durus), vessels feel rigid even between pulse beats. A form or contour of a pulse is palpatory estimation of arteriogram . A quickly rising and quickly falling pulse (pulsus celer)

3835-548: The pulse rate is close to the heart rate , as measured by ECG . Measuring the pulse rate is therefore a convenient way to estimate the heart rate. Pulse deficit is a condition in which a person has a difference between their pulse rate and heart rate. It can be observed by simultaneous palpation at the radial artery and auscultation using a stethoscope at the PMI, near the heart apex , for example. Typically, in people with pulse deficit, heart beats do not result in pulsations at

3900-417: The reconstruction of both form and function of the native and dysfunctioning aortic valve. Most frequently it is applied for the treatment of aortic regurgitation. It can also become necessary for the treatment of an aortic aneurysm, less frequently for congenital aortic stenosis.   In adults, symptomatic severe aortic stenosis usually requires aortic valve replacement (AVR). While Surgical AVR has remained

3965-558: The second heart sound (positive likelihood ratio, 3.1–50). Other peripheral signs include: For asymptomatic severe aortic valve stenosis, the European guidelines recommend B-type natriuretic peptide ( BNP ) measurements to aid risk stratification and optimize the timing of aortic valve replacement surgery . In patients with non-severe asymptomatic aortic valve stenosis, increased age- and sex adjusted N-terminal pro-brain natriuretic peptide ( NT-proBNP ) levels alone and combined with

4030-501: The top of the person's leg and proceed to insert the balloon into the artery. The balloon is then advanced up to the valve and is inflated to stretch the valve open. Acute decompensated heart failure due to AS may be temporarily managed by an intra-aortic balloon pump while pending surgery. In those with high blood pressure nitroprusside may be carefully used. Phenylephrine may be used in those with very low blood pressure. If untreated, severe symptomatic aortic stenosis carries

4095-477: The velocity of the blood through the valve, the pressure gradient across the valve can be calculated by the continuity equation or using the modified Bernoulli's equation : Gradient = 4(velocity)² mmHg A normal aortic valve has a gradient of only a few mmHg. A decreased valvular area causes increased pressure gradient, and these parameters are used to classify and grade the aortic stenosis as mild, moderate or severe. The pressure gradient can be abnormally low in

4160-470: The ventricle will occur, and a third heart sound may be manifest. Finally, aortic stenosis often co-exists with some degree of aortic insufficiency ( aortic regurgitation ). Hence, the physical exam in aortic stenosis may also reveal signs of the latter, for example, an early diastolic decrescendo murmur. Indeed, when both valve abnormalities are present, the expected findings of either may be modified or may not even be present. Rather, new signs that reflect

4225-466: Was found associated with an increased 5-year event rate of ischemic cardiac events ( myocardial infarction , percutaneous coronary intervention , or coronary artery bypass surgery ). Although aortic stenosis does not lead to any specific findings on the electrocardiogram (ECG), it still often leads to a number of electrocardiographic abnormalities. ECG manifestations of left ventricular hypertrophy (LVH) are common in aortic stenosis and arise as
