What is Gallop
A pair of extra HEART SOUNDS the cardiologist can hear with the bell of the STETHOSCOPE during diastole, so-named because they occur in rapid succession and sound like the hooves of a galloping horse. The characteristic sound is that of a deep-toned thud. A gallop often exists with tachycardia (rapid, regular HEART RATE) and generally signals ventricular dysfunction such as might follow HEART ATTACK.
