Question 1

what is a neck murmur?

Accepted Answer

Bruit: A murmur that arises in a blood vessel (instead of the heart) is called a bruit (pronounced "brew-eee"). It is due to turbulence, usually from a blockage. In the neck, the culprit is the carotid artery.

Question 2

can flow murmurs harm you?

Accepted Answer

No: A nl  flow murmur is benign.

Question 3

what is an end-systolic murmur?

Accepted Answer

Probable MVP: Mitral valve prolapse- a relatively benign abnormality- classically has a physical exam which includes a late systolic click followed by a murmur. My best guess is that is what an end-systolic murmur refers to.

Question 4

what causes late systolic murmur?

Accepted Answer

Classic: The classic answer is mitral valve prolapse.

Question 5

how come we got diastolic murmurs?

Accepted Answer

Diastolic murmurs: Flow occurs during ventricular diastole as the ventricles fill.  Abnormal mitral/tricuspid stenosis can produce such a murmur with impaired diastolic filling, while regurgitation across the aortic/pulmonary valves can accentuate flow into ventricles also producing a murmur.

Question 6

how's an functional murmur diagnosed?

Accepted Answer

Auscultation: Auscultation of the heart and echo.

Question 7

what is the systolic in systolic murmur?

Accepted Answer

Pumping Time!: The ventricles of the heart pump blood to the lungs and to the rest of the body. The portion of the cardiac cycle where they fill with blood is known as diastole. The portion where they contract to push that blood forward is known as systole. A murmur which occurs during this portion of the cardiac cycle is known as a systolic murmur.

Question 8

what disease is caused by holosystolic murmurs?

Accepted Answer

Murmurs: Holosystolic murmurs are heart sounds associated with insufficiency of the atrioventricular valves and ventricular septal defects. There are other possible holosystolic murmurs but these are the bulk of them. The murmur is purely sound and causes no problem. The physiologic problem causing the sounds is what causes the problem.

Question 9

what medications can treat a pansystolic murmur?

Accepted Answer

Murmur: Heart murmur is noise caused by turbulent blood flow in and around the heart. In timing there are systolic, diastolic and continuous murmurs. By cause there are too many to enumerate here. More information is needed to discuss physiology and treatment

Question 10

do people with cardiomyopathy usually have a murmur?

Accepted Answer

Not necessarily : Depends on the type and severity  of the cardiomyopathy.  If its dilated cardiomyopathy (big heart and poor function) there will be a murmur if there's associated mitral valve leakage. With hypertrophic cm (thick heart muscle with good function) there may not be a murmur, could be intermittent depending on position/posture, or fixed. There could also be other abnormal sounds such as a gallop.
