There are 3 distinct types of gallop rhythms. They are?

• A. ventricular gallop rhythm, atrial gallop rhythm, summation gallop rhythm
• B. systolic gallop rhythm, diastolic gallop rhythm, continuous gallop rhythm
• C. S1, S2, S3
• D. Murmurs, rubs, clicks

Answer: (A)

Gallop rhythms are extra heart sounds that reflect abnormal ventricular filling dynamics. There are three recognized types: a ventricular gallop, an atrial gallop, and a summation gallop. The ventricular gallop comes from S3, which appears in early diastole after the normal S2 when rapid filling occurs in a dilated or volume-overloaded ventricle. The atrial gallop is S4, heard just before S1, produced by atrial contraction pushing blood into a stiff or hypertrophied ventricle. The summation gallop occurs when S1, S2, and the extra sound overlap so closely that they merge into a single rapid cadence, often seen with very fast heart rates or marked diastolic dysfunction. This combination—ventricular gallop rhythm, atrial gallop rhythm, and summation gallop rhythm—is why that option is correct. Other choices refer to normal heart sounds (S1, S2, S3) or to non-gallop auscultatory findings like murmurs, rubs, and clicks, which are not gallop rhythms.
