Ventricular gallop occurs in which stage of the cardiac cycle?

• A. Late in diastole
• B. Late in systole
• C. Early in diastole
• D. Early in systole

Answer: (C)

Ventricular gallop is an abnormal heart sound that can be heard during the early phase of diastole, just after the normal heart sounds S1 and S2. This phenomenon occurs when blood rapidly fills the ventricles during the initial part of diastole, leading to vibrations of the ventricular walls and resulting in a distinct sound. During this time, the ventricles are in a relaxed state, allowing blood from the atria to flow into them. The sound is often described as a "galloping" rhythm and is commonly represented as "S3" in auscultation. It can be associated with conditions such as heart failure or volume overload states, where the rapid influx of blood causes these vibrations. Understanding the timing of this sound within the cardiac cycle is important for clinicians as it can indicate underlying heart conditions that may need further evaluation.
