Most of the time the heart can hold a beat, but sometimes it can sound off-rhythm or wonky. Learn about abnormal heart sounds in today's #ClinicalCuts!

If you put a stethoscope over the chest, you’ll usually hear something that sounds like "lub dub, lub dub, lub dub," which repeats over and over again with each cardiac cycle, or heartbeat.

In total, our heart has four valves.
• Two atrioventricular valves on the left side, between the atria and the ventricles: the tricuspid valve and the mitral valve
• Two semilunar valves, between the ventricles and the large arteries coming off of them: the pulmonary valve (right side) and the aortic valve (left side)

Normally in every heartbeat, some valves open and allow blood to pass through, and others close to hold blood within a chamber. The sound of the closing of each of these valves is projected onto the chest wall.
