First heart sound (S1) is generated by two heart valves: the mitral valve and tricuspid valve. Nearly simultaneous closing of these valves normally generates a single S1 sound. Splitting of the S1 sound is heard when mitral and tricuspid valves close at slightly different times, with usually the mitral closing before tricuspid
yotsubatoThen why the fuck is it describing a mitral valve sound in the tricuspid area +42019-06-16T12:21:53Z
dr.xxit's describing a splitting S1 — consisting of mitral and tricuspid valve closure — that is best heard at the tricuspid (left lower sternal border) and mitral (cardiac apex) listening posts.+22019-06-17T15:56:10Z
titanesxvitricky question, I though what sound it is in the left sternal border, so I chose tricuspid valve, but what they where asking was, what is the first component of the S1 sound+2019-10-16T15:28:19Z

Q: Split S1 heard over Left sternal border - tricuspid area. First component of S1?
A: anything (MC in RBBB) that causes delayed closure of tricuspid valve compared to mitral valve- will cause split S1 with delayed T1 and early M1 heard at Tricuspid area.
