It can increase the range of diaphragm activity by about 4 cm, and obviously improve lung function and oxygen uptake. Aerobic exercise needs a lot of oxygen to participate in fat metabolism, so aerobic exercise must use abdominal breathing. It can suppress the heart, so it can slow down the heartbeat. Bradycardia caused by hyperactivity of vagus nerve has a regular rhythm, usually 30 ~ 40 times per minute. This situation is more common in the elderly. However, if someone is responsible for your posture at some time before the physical examination (that is, you are required to stand still for a certain time), then go to the physical examination. That's your normal state. Appropriate drugs are needed to raise the heart rate, such as xinbao pills and salbutamol. However, if the heart rate continues to slow down to below 35 beats/min, permanent pacemaker implantation should be considered.

Congenital bradycardia does not require special treatment. If the original heart rate is normal, then it is bradycardia, which can be adjusted by taking drugs that invigorate qi and nourish blood. If there is any discomfort, stop immediately and wait for its relief. If this happens every time, go to the hospital for professional advice from a cardiologist. In the first few years, the doctor always wrote bradycardia on the examination report and suggested that I go to the hospital for reexamination. I told the doctor in advance during the physical examination in recent years. The doctor didn't ask me to check again. Personal opinion, for reference only. Thank you. If it is pathological, we need to do some cardiac electrophysiological tests, such as electrocardiogram and dynamic electrocardiogram, to find out what causes it, and also to find out whether medication is needed.

Therefore, a slow heartbeat will cause systemic ischemia and hypoxia, and nutrition and oxygen can't keep up. If it goes on for a long time, it will cause a series of pathophysiological reactions and cause harm to the body. For example, there are serious diseases such as hypoxia, hypothermia, hypothyroidism, obstructive jaundice, and some drugs to slow down the heart rate. Whether bradycardia needs medication depends on the specific situation.
