The maximum heart rate is mainly limited by the absolute refractory period (ARP) of the heart. Theoretically, the maximum conductivity is limited to about 300 times per minute. However, there are several cases in the literature that reported heart rates exceeding 300 beats per minute.
The fastest reported human heart rate was recorded in 20 12 by telemetry technology in a quadriplegic male patient with a history of atrial fibrillation in India. The average ventricular rate is about 600 beats per minute with transient syncope.
The patient was discharged two days after coronary intervention. His clinical manifestations remained stable, and he refused to accept further diagnostic research.
Heartbeat, as the name implies, is the beating of the heart. The right atrium receives venous blood from the whole body and pumps it out of the pulmonary artery through the right ventricle. At this time, venous blood flows in the pulmonary artery, becomes arterial blood rich in oxygen through gas exchange in the lung, is sent to the left atrium from the pulmonary vein, and is pumped to various tissues and organs of the whole body through the aortic pump of the left ventricle to meet the needs of normal physiological activities.
An adult's heartbeat is about seventy or eighty beats per minute, which is normal between 60- 100. In normal times, if an adult's heartbeat exceeds 100 times per minute when he is quiet, it is medically considered as "tachycardia"; Less than 60 times is "bradycardia".
Jump faster at work than at rest, women jump faster than men, children jump faster than adults, and newborns can jump 150 times per minute.
An average person lives 100 years old, so the total number of heartbeats can reach about 4 billion. Because athletes often exercise, the myocardial contractility is great, and the diastolic blood volume is also great, so in calm, the heartbeat is less than 60 beats/min, which can ensure the blood supply of the body, and some can be 48-50 beats/min. They only have the ability and endurance when they exercise.
