The normal heart rate is 60- 100 beats per minute, because the elderly's metabolism and aging heart rate are slow, which may also indicate that the newborn's heart rate is faster, but there is no boundary between good and bad heart rate, because everyone's individual differences are great, so heart rate is not an indicator of cardiovascular disease. Measure your heart rate, feel your pulse, or listen to your heartbeat and record the number of times you beat within 60 seconds.
There are many factors that affect your heart rate, including nerves, body fluids, body temperature, etc., but there is a saying that the slower your heart rate, the longer your life span, but this only applies to ordinary warm-blooded mammals, not to us. Because there is no scientific theory to prove that there is a direct relationship between human heart rate and life span. People who have been engaged in manual labor and sports for a long time generally have a slow heartbeat, which is the heartbeat of athletes. This is physiological bradycardia. Of course, except for athletes' heartbeats, a slow heartbeat is generally benign. If they don't have any symptoms, they just have a slow heartbeat without treatment. It is best to go to the hospital for 24-hour continuous ECG monitoring and examination.
In fact, rapid heartbeat and palpitation are common symptoms of many people. They are the body's response to the external environment or its own changes, which can be relieved by proper rest. A few people's palpitations may be due to heart disease or other systemic diseases, such as hyperthyroidism or anemia. If palpitation symptoms are common, or last for a long time, or accompanied by chest pain, dizziness, asthma and other uncomfortable symptoms, you should seek medical advice in time to find out the possible causes of tachycardia.
