On occasion the first heart sound can be made up of two separate sounds separated by a very small interval (20-30 milliseconds). S1 splitting is normal in many patients and is thought to be caused by mitral valve closure followed by an aortic ejection sound. You must first listen to many different normal heart sounds. What is it caused by? Here, you can find more information and a good example of the normal splitting of S1. The first heart sound (S 1) is produced by vibrations generated by closure of the mitral (M 1) and tricuspid valves (T 1 ). Synonym(s): second sound Diagnostik / Kardiologie.

A chapter is devoted to the esophageal phonocardiography. The book can provide useful information to cardiologists, doctors, students, and researchers. The second heart sound (S2) represents closure of the semilunar (aortic and pulmonary) valves (point d). Right bundle branch block can produce a split first heart sound - because the contraction of the right ventricle is delayed- the conduction occurs via the left ventricle rather than the bundle of His- and thefore the closure of the tricuspid valve occurs after a substantial delay.
