Which of the following is a common cardiac sign of Congestive Heart Failure (CHF)?

A common cardiac sign of Congestive Heart Failure (CHF) is the presence of an S3 heart sound, which is often referred to as a "ventricular gallop." This particular sound occurs when blood flows rapidly from the atria into a dilated ventricle during the early phase of diastole. The S3 sound is typically associated with volume overload of the ventricles, which is a hallmark of CHF, indicating that the heart is failing to pump efficiently and is becoming congested with fluid.

Identifying an S3 heart sound in the context of CHF can help clinicians recognize the severity of heart failure and guide appropriate management strategies. Understanding this sign also emphasizes the importance of auscultation in assessing heart health in patients with potential heart failure symptoms. The S3 sound is usually better heard in left lateral decubitus position and can suggest poor ventricular function, highlighting the need for further evaluation and possible intervention.

The other options present different conditions or signs that are not exclusively linked to CHF. For instance, coronary vasospasm is related to ischemic heart disease, stable angina pertains to predictable chest pain during exertion, and Levine's sign indicates a patient’s experience of chest pain. While these may present in various cardiac
