| How to judge whether the heart rate bpm is normal |
Heart rate refers to the number of beats per minute in a normal person's quiet state, also known as a quiet heart rate, generally 60 to 100 beats / min;
Individual differences can occur due to age, gender, or other physiological factors.
In general, the younger the age, the faster the heart rate, the older people's heartbeat is slower than the younger, and the female's heart rate is faster than that of the same age. These are normal physiological phenomena.
In a quiet state, the normal heart rate of an adult is 60-100 beats/min, and the ideal heart rate should be 55-70 beats/min (the athlete's heart rate is slower than that of an ordinary adult, generally about 50 beats/minute).
1. Heart rate normal range:
There is a significant individual difference in heart rate in normal adults when they are quiet, with an average of 75 beats/min (60-100 beats/min). Heart rate can vary with age, gender, and other physical conditions. The heart rate of newborn children is very fast, up to 130 beats / min.
In adults, women's heart rate is generally slightly faster than men's. In the same person, when the heart rate is slow or sleep, the heart rate is slowed down, and the heart rate is accelerated during exercise or emotional excitement. Under the influence of certain drugs or neurohumoral factors, the heart rate may be accelerated or slowed down. People who often perform physical labor and physical exercise usually have a slow heart rate.
In recent years, a large sample of healthy population surveys in China found that the normal range of resting male heart rate is 50-95 beats/min, and females are 55-95 beats/min. Therefore, heart rate changes with age, gender and health status.
2. The clinical significance of detecting heart rate:
Slow heart rate
The number of heartbeats in normal people is 60-100 beats/min. Less than 60 is called bradycardia. There are several types of bradycardia, the most common being sinus bradycardia.
Sinus bradycardia can be divided into pathological and physiological. Physiological sinus bradycardia is a normal phenomenon. The general heart rate and pulse rate are 50-60 beats/min. The athlete may have 40 heart rate. Without treatment, it is common in normal people who sleep and have more physical activity. Heart rate or pulse is less than 50 times. Most of them are pathological and require treatment. In severe cases, a pacemaker should be installed to speed up the heart rate.
Heart rate overspeed
Adults have a heart rate of more than 100 beats per minute, called heart rate overspeed. Heart rate is divided into two types: physiological and pathological. Physiological heart rate tachycardia is very common, and many factors affect heart rate, such as body position changes, physical activity, food digestion, emotional anxiety, pregnancy, excitement, fear, agitation, drinking, smoking, drinking tea, etc., can increase heart rate fast. In addition, age is also a factor, and children's heart rate tends to be faster.
Pathological heart rate tachycardia can be divided into sinus heart rate tachycardia and paroxysmal supraventricular tachycardia. The characteristic is that the heart rate is faster and slower. It is gradually carried out. Generally, the heart rate per minute will not exceed 140 times. Most of them have no organic heart disease. The patients generally have no obvious discomfort, and sometimes have symptoms such as palpitation and shortness of breath. If you have a persistent tachycardia, you must identify the cause and treat the cause early.
3. Heart rate is an effective indicator for predicting men's life:
Humans and mammals are very different. Under similar heart rate conditions, people's life expectancy is much longer than that of animals. The main reasons are scientific development, medical care and social progress.
The resting heart rate of 5360 healthy adults was observed, ranging from 51 to 94 beats/min, with an average of 67 beats/min. The number of human heartbeats is obviously affected by autonomic and humoral factors. If people are excited, their heart rate will increase, and when they are completely quiet, their heart rate will slow down. Scientific research shows that the adult resting heart rate is 70 beats / min, and its life expectancy can reach 80 years old (note that the interference of various diseases should be excluded).
The above is an introduction about how to judge whether the heart rate bpm is normal, and the heart rate is also closely related to people's activities and diet. In life, we must maintain good living habits and care for the health of the heart. If the heart rate is abnormal during the examination, it is necessary to distinguish whether it is physiological or pathological, so that symptomatic treatment is good.
Heart rate abnormality related factors
Heart rate changes are closely related to heart disease. If the heart rate exceeds 160 beats / minute, or less than 40 beats / minute, most of them are seen in patients with heart disease. If they are often accompanied by discomfort such as palpitations and chest tightness, detailed examination should be carried out as soon as possible in order to treat the cause.
1.Tachycardia
Adults have a heart rate of more than 100 beats per minute (generally no more than 160 beats per minute), called sinus tachycardia, which is common in excitement, excitement, smoking, drinking, drinking tea or coffee, or in infection, fever, Under the pathological conditions of shock, anemia, hypoxia, hyperthyroidism, heart failure, or after the application of atropine, adrenaline, ephedrine and other drugs.
2. Bradycardia
When the adult is quiet, the heart rate is lower than 60 times/min (generally 45 times/min or more), which is called sinus bradycardia. It can be seen in healthy people and athletes who have been engaged in heavy physical labor for a long time; or seen in hypothyroidism and intracranial pressure. Increased, obstructive jaundice and digitalis, quinidine or propranolol overdose. If the heart rate is less than 40 times / minute, you should consider the situation of sick sinus syndrome, atrioventricular block and so on. If the pulse strength is not equal, the pulse rate is less than the heart rate, atrial fibrillation should be considered.
3. Correct view of sinus bradycardia
Many people have sinus bradycardia and are not normal. For most people, it is normal, don't worry too much. Sinus bradycardia refers to people with a heart rate below 60 beats/min. Whether this symptom will occur is related to the frequency of heartbeat and the cause of heartbeat. In a quiet state, if the heart rate of an adult is between 50 and 60 beats per minute, there will be no obvious symptoms. In particular, some well-trained athletes and those who have been engaged in manual labor for a long time will not have obvious symptoms even if their heart rate is around 40 times/minute in a quiet state. However, if the heart rate of the average person is between 40 and 50 times per minute, symptoms such as chest tightness, fatigue, and dizziness may occur. If the heart rate drops to 35 to 40 times per minute, hemodynamic changes may occur, and the heart and brain organs may be caused. The blood supply is affected, resulting in chest pain, dizziness, syncope and even sudden death. If you feel that you don't feel any discomfort, you don't need to pay attention to the "sinus bradycardia with irregularity" as mentioned in the electrocardiogram. However, if you have symptoms such as chest tightness, fatigue, dizziness, etc., you should go to the hospital for further examination, such as dynamic electrocardiogram and cardiac ultrasound. Check to understand the cause of bradycardia. If the heart skips slowly, you can relieve the symptoms and improve the prognosis by installing a cardiac pacemaker.
Heart rate daily care
Increased heart rate harms health, shortens life expectancy, and increases the incidence and mortality of cardiovascular disease. How can I keep the resting heart rate at around 60 times/minute:
1.Exercise
Often participating in a variety of exercises of appropriate intensity will slow the resting heart rate. Although the heart rate is increased during exercise, exercise can exercise the heart function, thereby slowing the resting heart rate. The general suitable exercise heart rate is "170-age". For example, a 50-year-old person should have a controlled exercise rate of 120 beats per minute. If the exercise rate is too high, the amount of exercise will be too large. Be conscious and comfortable before exercise, no fatigue, generally do not exercise for more than 1 hour, and the best time is 30 minutes to 60 minutes, at least 3 times a week.
2. Correct bad lifestyle
Staying up late, smoking, drinking can make the resting heart rate faster. Drink less tea, especially if you don't drink before going to bed, otherwise it will lead to insomnia. You should also regular stools to keep your bowel movements smooth.
3. Maintain proper weight
Obesity increases the burden on the heart and speeds up the heart rate. Therefore, obese people need to exercise and adjust their diet to maintain a proper weight.
4. Keep your mind calm
The central state of life should be calm, don't always worry, get angry, if the heart rate is too fast because of nervousness, anger, etc., you can gradually restore calm by listening to music, meditating and other ways.
5. Drug treatment
Some diseases, such as hypertension and coronary heart disease, increase heart rate, can take drugs according to doctor's advice, slow heart rate, protect the heart, reduce and control myocardial ischemic events, improve heart function and prolong life.
