In healthy individuals, S2 is often heard as a single sound during expiration. However, during , a "split" S2 can be heard. This is a normal finding, especially in children and young adults.
S2 is composed of two distinct components:
The second heart sound, commonly referred to as S2, is a crucial component of the cardiac cycle, playing a significant role in the assessment of heart health. It is one of the two primary heart sounds heard through a stethoscope during auscultation, the other being the first heart sound (S1). S2 is associated with the closure of the aortic and pulmonary valves, marking the end of systole and the beginning of diastole in the heart's cycle. s2 heart sounds
Abnormalities of the S2 heart sound can be classified into several categories:
Anything that further delays right ventricular emptying. 📍 How to Auscultate S2 In healthy individuals, S2 is often heard as
A2 is delayed so significantly that it occurs after P2. Inspiration moves P2 closer to the delayed A2, making the sound appear unified. 3. Wide Splitting
To accurately assess the S2 sound, clinicians use the diaphragm of the stethoscope, which is best for high-pitched sounds. S2 is composed of two distinct components: The
