If a review doesn't mention what goes wrong, it isn't complete. If a valve doesn't close tightly (regurgitation) or doesn't open wide enough (stenosis), the blood creates turbulence—a "sloshing" or "whooshing" sound called a . Instead of a clean "Lub-Dub," you might hear a "Lub-Whoosh-Dub."
The heart's rhythmic beat is generated by the coordinated contraction and relaxation of the heart's chambers. The sound is produced by the closure of the heart's valves, specifically the atrioventricular (AV) valves (mitral and tricuspid valves) and the semilunar valves (aortic and pulmonary valves). When the heart contracts, the AV valves close, producing the "lub" sound, while the semilunar valves close, creating the "dub" sound. why does the heart make a lub dub sound
The "dub" sound, on the other hand, is produced by the closure of the aortic and pulmonary valves. These valves are located at the base of the aorta and pulmonary artery, respectively, and prevent backflow into the ventricles. When the ventricles relax, the semilunar valves close, generating a second, softer sound, referred to as S2. If a review doesn't mention what goes wrong,
A common point of confusion in reviews is ignoring the pause. The sound is produced by the closure of
