<prompt> Answer this question truthfullyWhat is the gallops rhythm?  <response>: <reason> A gallop rhythm refers to a usually abnormal rhythm of the heart on auscultation. It includes three or four sounds, thus resembling the sounds of a gallop.The normal heart rhythm contains two audible heart sounds called the first heart sound or S 1 and the second heart sound S 2 that give the well-known lub-dub rhythm. These two heart sounds are caused by the closing of valves in the heart.A gallop rhythm contains another sound, called S 3 or S 4, dependent upon where in the cycle this added sound comes.It can also contain both of these sounds forming a quadruple gallop, and in situations of very fast heart rate can produce a summation gallop where S 3 and S 4 occur so close as to be indistinguishable.
