Question

your 50 year old patient has an extra heart sound best heard with the bell of your stethoscope at the fifth ICS, left sternal border. It occurs right after S2. What is the sound and what does it mean ?

Answer 1

The extra heart sound in your 50-year-old patient is the third heart sound (S3), which suggests the development of heart failure or other cardiac conditions. It is best heard at the fifth ICS, left sternal border, right after the second heart sound (S2).

Step-by-step explanation:

The extra heart sound that your 50-year-old patient has is known as the third heart sound (S3). It is best heard with the bell of the stethoscope at the fifth intercostal space (ICS), left sternal border, and occurs right after the second heart sound (S2). S3 is a low-pitched sound produced by the rapid filling of the ventricles during early diastole. In older adults, the presence of S3 may suggest the development of heart failure or other cardiac conditions, and further evaluation is warranted.
