Which statement about the S3 heart sound is incorrect?

A) It occurs early in diastole
B) It’s normal in children and young adults
C) It can be a normal variant for anyone over 40
D) It may signify congestive heart failure

The correct answer is: C) It can be a normal variant for anyone over 40

The assertion about the S3 heart sound being a normal variant for anyone over 40 is considered incorrect because, while the S3 sound can be heard in healthy younger individuals, its presence in older adults is often more concerning. In individuals over the age of 40, the S3 gallop can indicate volume overload or heart failure rather than just a normal variant. In younger populations, especially children and pregnant women, the S3 sound is frequently benign due to a compliant ventricle. However, in adults over 40, the context of the S3 sound may be significant, particularly if it is associated with heart failure symptoms or other cardiovascular issues. Thus, it's essential to assess the clinical situation of the patient to determine if the S3 sound is pathological or a sign of underlying issues.
