The murmur usually does not extend to S1. Early diastolic Left anterior descending artery stenosis This murmur, also known as Dock's murmur, is similar to that of aortic regurgitation and is heard at the left second or third intercostal space. A Coronary artery bypass surgery can eliminate the murmur. Early diastolic Cabot–Locke murmur
Bruit, also called vascular murmur, [3] is the abnormal sound generated by turbulent flow of blood in an artery due to either an area of partial obstruction or a localized high rate of blood flow through an unobstructed artery.
Heart murmurs are unique heart sounds produced when blood flows across a heart valve or blood vessel. [1] This occurs when turbulent blood flow creates a sound loud enough to hear with a stethoscope. [2] The sound differs from normal heart sounds by their characteristics. For example, heart murmurs may have a distinct pitch, duration and timing.
Systolic heart murmurs are heart murmurs heard during systole, [1] [2] [3] i.e. they begin and end between S1 and S2. Many involve stenosis of the semilunar valves or regurgitation of the atrioventricular valves .
Phase III: The return of sharper sounds, which become crisper to regain, or even exceed, the intensity of Phase I sounds. Phase IV: The distinct abrupt muffling of sounds, which become soft and blowing in quality. Phase V: The point at which all sounds finally disappear completely is the diastolic pressure.
The physical symptoms, like a sudden drop in blood pressure, may signal to the brain that something is very wrong, says Hafeez. It may also be the release of hormones from the adrenal glands ...
In terms of the cause of aortic regurgitation, is often due to the aortic root dilation (annuloaortic ectasia), which is idiopathic in over 80% of cases, but otherwise may result from aging, syphilitic aortitis, osteogenesis imperfecta, aortic dissection, Behçet's disease, reactive arthritis and systemic hypertension.

A 2011 autopsy-based study found that sudden death was attributed to a cardiac condition in 79.3% of cases, and was unexplained in 20.7%. [3] In the Philippines, sudden adult death syndrome (or in their term, bangungot) is mainly caused by the Brugada syndrome. [14]
