Question

What is the difference between korotkoff sounds and lub and dub sound Give reasons.

Answer 1

Explanation:

Korotkoff sounds are heard at the point where the systolic pressure exceeds the cuff pressure, and blood passes in turbulent flow through the partially constricted artery while 'lub' and 'dub' that are due to vibrations inside the ventricles that are associated with the sudden shut of the valves.

Answer 2

Explanation:

The two major sounds heard in the normal heart sound like " lub, dub". The lub is the first heart sound commonly terned si and is caused by the closer of mital and tri cuspid valves at the start of systole. The second sound"dub" or S2 is caused by the closer of arotic and pulmonic valves, marking the end of systole. Thus the time period clasping between the first heart sound and second sound defines ( ventricular ejection) and the time between the second sound and the following first sound defines diastole (ventricular feeling).

There is also a third and a fourth heart sound,S3 and S4. They can occur in normal person or be associated with the pathalogical process of theirof cedense or rhythmic timing S3 and S4 are called gallops. Gallops are low frequency sounds that are associated with diastole feeling.
