Heart Murmur
Heart Murmur
An unusual "whoosh" sound during a heartbeat, caused by turbulent blood flow in the heart.
1st Heart Sound (S1)
1st Heart Sound (S1)
The "lubb" sound, created by the closing of AV valves at the start of ventricular contraction.
2nd Heart Sound (S2)
2nd Heart Sound (S2)
The "dupp" sound, created by the closing of semilunar valves at the beginning of ventricular relaxation.
