201:, can be normal, especially in children, or with severe exercise, but are generally heard (on the left side) when ventricular function is impaired, e.g., in case of acute infarction or severe cardiac failure. The sounds are thought to be caused by the atrium, facing back-pressure, forcing volume into an incompletely emptied ventricle. Then, given tachycardia, a "gallop" is produced. With right-sided back pressure after pulmonary embolism, and therefore an incompletely emptied right ventricle, a right-sided gallop can occur.
