A continual "lub-dub, lub-dub" is a common way to characterize the sounds. The mitral valve and tricuspid valve closing is the source of the first "lub-dub." Following the first "lub-dub," the second "lub-dub" is made by the aortic and pulmonary valves shutting.
A blood backflow brought on by the heart's mitral valve failing to seal securely. When the mitral valve of the heart fails not close completely, blood can flow backward inside the heart, a condition known as mitral valve regurgitation. Breathing difficulties, weariness, dizziness, and an erratic, fluttering heartbeat are all symptoms. Treatment might not be necessary for everyone. Between the heart's two right chambers is where the tricuspid valve is located. There are three little flaps of tissue that make up the tricuspid valve (called cusps, or leaflets). These valve flaps open to let blood to flow from the right atrium, which is the upper chamber, to the right chamber, which is the lower chamber (right ventricle).
