2- Heart rate, heart sound and murmurs
... The duration of the 1st. heart sound (0.14 second), is longer than the second heart sound (0.11 second); this is because the semilunar valves are tauter than AV valves, so they vibrate for short period than do AV valves. The first heart sound has a lower frequency (pitch) which is 25-45 Hz than seco ...
