![]() A heart condition is one in which the heart does not work properly. The leading cause of death in the United States is heart disease. The extent of damage to the heart muscle can be determined by analyzing the sound of heart sounds. Other factors can also be considered when determining the severity of a heart attack. A heart sound can be used to determine how well the heart pumps blood in addition to assessing its function. Using heart sounds, a method of determining the extent of damage to a heart muscle can be developed. A heart sound can be used to diagnose heart disease and determine the efficiency of the heart. When a heart muscle contracts and makes noises, it produces sound waves. The most common sounds found in the heart are ‘lub’ and ‘dub.’ Some healthy people may hear the sounds of the third and fourth heart beats, but this can indicate a problem with the heart. It is normally heard best at the apex of the heart, which is located at the left fifth intercostal space.Īn examination of the heart sounds is essential in diagnosing and assessing heart health. The s1 heart sound is produced by the closure of the atrioventricular valves. Dubs made from these sounds are frequently referred to as lubs. When the mitral and tricuspid values close, turbulence causes the first heart sound. S1 can be best heard over the apex if you use a stethoscope’s bell or diaphragm. S1 is a low frequency sound that occurs at the beginning of systole. The S1 wave is generated by the closure of mitral and tricuspid valves, which are located at the apex of the heart. Sound from the apex to the bottom of the heart. ![]() S1 beats S2 when the topmost heart beat is louder than the base beat. The topmost heart beat is usually louder than the base beat. So, S1 heart sound is produced when the tricuspid and mitral valves close and S2 heart sound is produced when the aortic and pulmonary valves close. S2, also known as “dub,” is the second heart sound, and is produced when the aortic and pulmonary valves close. S1, also known as “lub,” is the first heart sound, and is produced when the tricuspid and mitral valves close. There are two main types of heart sounds: S1 and S2.
