The pulse refers to the pulsation of the arteries, usually the radial artery on the inside of the wrist. Abnormal pulse rhythms respond to abnormalities in cardiac systole and diastole and include atrial premature beats, ventricular premature beats, ventricular fibrillation, atrial fibrillation, and electrical conduction block. A regular heartbeat followed by an advanced heartbeat is called duplex rhythm, and two regular heartbeats followed by an advanced heartbeat is called triplex rhythm. Abnormal pulse rhythm and dwarf pulse, when counting the heartbeat and pulse at the same time, the pulse rate is less than the heart rate is pulse dwarf, mostly seen in coronary heart disease or heart valve disease, coronary heart disease is related to greedy food, heart valve disease is long-term rheumatic fever damage to the valves. Abnormal pulse rhythm also has physiological causes, such as heavy drinking, staying up late, drinking strong tea, will return to normal after sufficient rest.
