1999 domestic diagnostic and classification standard of hypertension adopted by the world health organization and the world hypertension union: ideal blood pressure: systolic blood pressure.
An adult's heartbeat is about seventy or eighty beats per minute, but it is normal between 60- 100. Jump faster at work than at rest, women jump faster than men, children jump faster than adults, and newborns can jump 150 times per minute. An average person lives 100 years old, so the total number of heartbeats can reach about 4 billion.
In normal times, if the adult's heartbeat exceeds 100 times per minute when he is quiet, it is medically considered as "tachycardia"; Less than 60 times is "bradycardia". Some people's heart beats fast and slow, jumping and stopping These are all within the range of abnormal heartbeat. Abnormal heartbeat is one of the symptoms of heart disease.
However, like many organs of the body, the working ability of the heart can be changed, and it has a lot of room for expansion and contraction.
According to research, if you finish a set of broadcast gymnastics seriously, your heart rate may increase by twenty or thirty times per minute. When people are angry and afraid, when students are in the examination room, their heart beats faster. The heart rate of athletes climbing Mount Everest is 170 to 80 beats per minute. Let some people run 300 meters with a load of 30 kilograms, and their hearts beat more than 200 times per minute. Medical data recorded a heartbeat as high as 270 times.
The purpose of quickening the heartbeat is to send more blood to meet the needs of manual labor, sports and special circumstances. If the heartbeat is too small, the blood supply is insufficient, and the body can't get the necessary oxygen and nutrition, people can't live normally, and even lead to more serious consequences.
Physiologists have found that people who have been engaged in heavy physical labor and high-intensity exercise for a long time have exercised their hearts and their heartbeat times are much less than ordinary people. There is a football player in our country today. His heartbeat is only 37 times per minute. 1928 At the Olympic Games, an athlete only played 28 times a minute. The results show that people who get better heart exercise have thicker myocardial fibers, thicker ventricular walls and larger hearts themselves. After a former British world marathon champion died of cancer at the age of 70, doctors found that his heart was about 30% heavier than that of normal people, and the feeding artery-coronary artery was about 1 times. This kind of heart naturally contracts badly, and every time it beats, it sends twice as much blood to the whole body as ordinary people. So although I jump less, I can meet the normal needs of my body because of my blood.
There are several types of bradycardia, the most common being sinus bradycardia. Sinus bradycardia can be divided into pathological type and physiological type. Physiological sinus bradycardia is normal. Generally, the heart rate and pulse rate are 50 ~ 60 beats/min. The athlete's heart rate may reach 40 times, which is very common in normal people with more sleep and physical activity and does not need treatment. Heart rate or pulse less than 50 times are mostly pathological and need treatment. In severe cases, a pacemaker should be installed to speed up the heart rate.
What should I do if I find sinus bradycardia by checking ECG?
1. Without heart discomfort, the pulse is 50 ~ 60 beats/min. This kind of sinus bradycardia is mostly physiological, that is, normal phenomenon, and there is no need to worry about affecting health or treatment.
2. For people with uncomfortable heart, first pay attention to the number of pulses when they are calm, and then pay attention to the number of pulses when they are uncomfortable. If the pulse rate decreases every time you feel uncomfortable, it means that your discomfort is caused by bradycardia and needs treatment. In severe cases, pacemakers should be installed to speed up the heart rate. You can also check the 24-hour electrocardiogram first to see how slow the heart rate is. It doesn't matter if the heart rate is uncomfortable. The pulse rate is 50 ~ 60 beats/min, indicating that bradycardia doesn't need treatment, and other tests are needed to confirm whether there is heart disease.
Treatment method 1
Shenfu decoction
Ginseng 30g, aconite 15g.
Usage: First, decoct ginger and jujube in water, remove residues and leave juice, then decoct ginseng and aconite with soup instead of water, and take the juice and drink it slowly.

This prescription was revised to treat this disease. Astragalus membranaceus mainly benefits qi, and is compatible with angelica tail, Radix Paeoniae Rubra, Semen Persicae and Carthami Flos. Promoting blood circulation and removing blood stasis, so that qi can be sufficient and blood is feasible, and blood stasis can dredge collaterals, which is its compatibility. In clinical application, hemiplegia, qi deficiency and blood stasis, pale tongue with white fur and slow pulse are the key points of syndrome differentiation.
