Which syllable is associated with S1?

Explanation:
S1 is the first heart sound produced when the atrioventricular valves (mitral and tricuspid) close at the start of ventricular systole. This creates the sound we describe as “Lub.” So the syllable linked to S1 is Lub. S2, heard as “Dub,” marks the closing of the semilunar valves at the end of systole. The syllables Ta and Tu aren’t used to label heart sounds.
