While auscultating a client's heart sounds, the nurse hears an extra heart sound immediately after the second heartsound (s2). an audible s3would be considered an expected finding in what client?



Answer :

An S3 heart sound would be considered a sign of systolic heart failure in a patient experiencing dilation of the left ventricle.

Heart sounds are generally produced due to the closing of the cardiac valves. Normal heart sounds are S1 and S2. Whereas S3 heart sound is more considered pathologic than to be normal and S4 heart sound is always pathological. This differentiation is made based on intensity, frequency, location, quality, and timing in the cardiac cycle.

The heart sound S1 is the result of the closing of mitral and tricuspid valves and sound S2, is the result of the closing of aortic and pulmonic valves. These two are often considered normal. The heart sound S3, if occurs, occurs after S2 as a result of an accidental opening of the mitral valve. This allows passive filling of the incapable left ventricle. It is caused due to a large amount of blood striking the LV.

Heart sound S3 is low-pitched and is also called a ventricular gallop. It often occurs as a sign of systolic heart failure while can be normal at other times.
