What is the heart rate standard for adults

The heart is a relatively important organ in our human body, but due to some irregular living habits in our lives, such as long-term smoking and drinking, it is particularly easy to cause heart disease. Sometimes we may have symptoms such as fast heartbeat or slow heartbeat. Irregular heartbeat is particularly likely to lead to heart disease, which seriously affects our physical health. Let us understand what the heart rate standard for adults is.

Heart rate refers to the frequency of heart beats, the number of times the heart beats per minute. A normal person's heart beats 60 to 100 times per minute when calm. During exercise, the heart rate will accelerate. Athletes with better cardiopulmonary function will have a slower heart rate than normal people.

Heart rhythm refers to the rhythm of the heartbeat and should not be confused with heart rate.

What is the heart rate standard for adults?

1. There are significant individual differences in the heart rate of normal adults at rest, with an average of about 75 beats/minute (between 60 and 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 quiet or sleeping, and speeds up when 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/minute, most of them are 60 to 80 beats/minute, and women are slightly faster; children under 3 years old are often above 100 beats/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.

We all know that a normal heartbeat is regular. If symptoms such as a fast or slow heart rate occur, timely treatment should be sought. After understanding the standard heart rate for adults, don't always think that it is no big deal when there is a heart problem. We must pay great attention to it. When we feel unwell, we must seek timely treatment. We must also maintain a good mood and try to stay away from tobacco and alcohol.
