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)

A gallop rhythm signals an extra heart sound tied to how the ventricle fills and how the atrium contributes to filling. There are three classic varieties. A ventricular gallop comes from rapid passive filling of a compliant ventricle and is heard after the second heart sound during early diastole as an S3. An atrial gallop arises from the atrial kick just before the next beat, heard before the first heart sound as an S4. A summation gallop happens when heart rate is so fast or both extra sounds are present that they merge into a single, blended sound.

This trio—ventricular gallop, atrial gallop, and summation gallop—is the standard way to categorize the three distinct gallop rhythms. Other sound categories, like murmurs, rubs, or clicks, are different phenomena and not the three gallop types. Similarly, S1 and S2 are normal heart sounds, not gallops, and there isn’t a separate, widely used category called a “systolic” or “diastolic” gallop in the same sense.
