Heart rate, that is, the frequency of heartbeats, is an important measure of human health. The heart rate has a certain normal value. If it exceeds this range, it means that there are certain problems with human health. You need to go to the hospital in time to check the cause and then receive treatment. So, what is the normal heart rate when a person is sleeping? The following is a detailed introduction. 1. What is heart rate? Heart Rate: A professional term used to describe the cardiac cycle, which refers to the number of heart beats per minute, based on the first sound. Heart rate. In modern Chinese, heart rate is interpreted as "the frequency of heart beating". Frequency is the number of times something happens per unit time. The two explanations combined mean the number of times the heart beats within a certain period of time, that is, how fast the heart beats within a certain period of time. 2. What is a normal heart rate when sleeping? The normal heart rate of a normal person at rest is about 60-80 beats/min for adult males and 70-90 beats/min for females. When falling asleep, the heart rate decreases to 50-70 beats/min for males and 60-70 beats/min for females. For some people, it can be as low as 45-50 beats/min. For infants, it is 120-140 beats/min. For 1-2 years old, it is about 110 beats/min. For 3-4 years old, it is 90-100 beats/min. For 5-6 years old, it is about 95 beats/min. For 7-8 years old, it is about 85 beats/min. For 9-15 years old, it is 70-80 beats/min. The heart rate of children can slow down by 10-40 beats/min when they are asleep. The heart rate can increase when standing, exercising, after meals, or when suffering from certain illnesses. 3. Standard heart rate 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. |
