Third heart sound gallop

The early diastolic galloping rhythm refers to the pathological third heart sound. It is the sound of early diastolic blood filling up to the enlarged ventricle and causing the wall vibration or the sound produced by the vibrating atrioventricular valve. It is often caused by severe myocardial damage, Left heart failure, valvular insufficiency, massive left-to-right shunt, etc. The bell-shaped auscultation head on the left side of the patient is the clearest auscultation at the apex of the heart, which is a low-key sound. If it is a right heart disease, it should be auscultated most clearly at the lower left edge of the sternum. The pathological third tone tends to be called the galloping rhythm clinically even if the heart rate is not fast. It is also called room running gallop. Because it is actually a rhythm composed of pathological S3 and S1, S2, it is also called the third heart sound galloping rhythm.
