Heart rate is within the normal range. Are you within the standard?

Heart rate is the number of times the heart beats per minute. The normal heart rate of an adult is 60-100 beats per minute. The speed of the heart rate is affected by age. The younger the age, the faster the heart rate. If the heart rate is too fast or too slow, it is necessary to check and treat it in time.

1. There are significant individual differences in the heart rate of normal adults at rest , with an average of around 75 beats/minute (between 60-100 beats/minute). Heart rate can vary depending on age, gender, and other physiological conditions. The heart rate of a newborn is very high, reaching over 130 beats per minute. Among adults, women generally have a slightly faster heart rate than men. For the same person, the heart rate slows down when the person is at rest or sleeping, and speeds up when the person is exercising or emotionally excited. Under the influence of certain drugs or neurohumoral factors, the heart rate can speed up or slow down. People who regularly engage in physical labor and exercise usually have a slower heart rate. In recent years, a large-sample survey of healthy people in China found that the normal range of resting heart rate for Chinese men is 50-95 beats/minute, and for women it is 55-95 beats/minute. So, heart rate varies with age, gender, and health status.

2. The heart rate of a healthy adult is 60 to 100 beats per minute, most of them are 60 to 80 beats per minute, and women are slightly faster; children under 3 years old are often above 100 beats per minute; the elderly are slower. A heart rate of more than 100 beats per minute in an adult (generally not more than 160 beats/minute) or more than 150 beats/minute in an infant is called sinus tachycardia. It is common in normal people after exercise, excitement, agitation, smoking, drinking and strong tea. It can also be seen in fever, shock, anemia, hyperthyroidism, heart failure and the use of atropine, epinephrine, ephedrine, etc.

If the heart rate is between 160 and 220 beats per minute, it is often called paroxysmal tachycardia. A heart rate lower than 60 beats/minute (generally above 40 beats/minute) is called sinus bradycardia. It can be seen in people who engage in heavy physical labor for a long time and in athletes; pathologically, it can be seen in hypothyroidism, increased intracranial pressure, obstructive jaundice, and overdose or poisoning of digitalis, quinidine, or propranolol. If the heart rate is less than 40 beats/min, atrioventricular block should be considered. A heart rate that is too fast, exceeding 160 beats/minute, or less than 40 beats/minute, is mostly seen in patients with heart disease. Patients often experience palpitations, chest tightness, and discomfort in the precordial area. A detailed examination should be conducted early so that treatment can be targeted at the cause. 3) The amount of blood pumped from the ventricles to the arteries each time the heart contracts is called the stroke volume, and the amount of blood pumped by the heart per minute is called the minute volume. The stroke volume of a normal person in a resting state is 70 ml. If the heart rate is calculated at 75 beats per minute, the minute volume is approximately 5250 ml. The amount of cardiac output is an indicator of the heart's working capacity.
