Detailed explanation-1: -Normal heart sounds come in pairs. The sounds are often described as a constant “lub-dub, lub-dub.” The first “lub-dub” is the sound of the mitral and tricuspid valves closing. The second “lub-dub” is the sound of the aortic and pulmonary valves closing soon after.
Detailed explanation-2: -The heart sounds are usually described as a lup-dup sound. These sounds are due to the closing of the valves of the heart. Unusual heart sounds are called murmurs.
Detailed explanation-3: -Heart sounds are created from blood flowing through the heart chambers as the cardiac valves open and close during the cardiac cycle. Vibrations of these structures from the blood flow create audible sounds-the more turbulent the blood flow, the more vibrations that get created.
