• Splitting of heart sounds Splitting of S1 : it is due to closure of MV and TV asynchronously loudest over the apex in RBBB
Splitting of s2 ) In normal person, physiologic splitting due to the closure of av and pv asynchronously in inspiration 2) In pathological situation delay of emptying time of one side of the heart such as ASD.Ms
• Splitting of S2 : 1) In normal person, physiologic splitting – due to the closure of AV and PV asynchronously in inspiration 2) In pathological situation – delay of emptying time of one side of the heart such as ASD,MS
