What is S3 in medical?

The third heart sound (S3), also known as the “ventricular gallop,” occurs just after S2 when the mitral valve opens, allowing passive filling of the left ventricle. The S3 sound is actually produced by the large amount of blood striking a very compliant left ventricle.

What is the cause of S3 heart sound?

Third Heart Sound S3 Results from increased atrial pressure leading to increased flow rates, as seen in congestive heart failure, which is the most common cause of a S3. Associated dilated cardiomyopathy with dilated ventricles also contribute to the sound.

Is S3 a diastolic murmur?

S3 and S4 are low-frequency diastolic sounds that originate in the ventricles.

What is the abbreviation of S3?

What causes S3 and S4?

CLINICAL PEARL: A S4 heart sound occurs during active LV filling when atrial contraction forces blood into a noncompliant LV. Therefore, any condition that creates a noncompliant LV will produce a S4, while any condition that creates an overly compliant LV will produce a S3, as described above.

What does S3 gallop mean?

Definitions. A ventricular gallop sound is an extra heart sound. There are two types of gallop sounds, S3 and S4. S3 gallop is a low frequency, early to mid-diastolic sound. This indicates slow filling caused by older age, hypertension, left ventricular hypertrophy (LVH), or diastolic dysfunction.

What does S3 mean heart?

Definition. The third heart sound (S3) is a low-frequency, brief vibration occurring in early diastole at the end of the rapid diastolic filling period of the right or left ventricle (Figure 24.1) Synonymous terms include: ventricular gallop, early diastolic gallop, ventricular filling sound, and protodiastolic gallop.
