Summer is the best way to get proper exercise, with a slight sweat. To get in touch with nature, you have to sleep at night and get up early in summer to achieve harmony. But heavy sweating is not recommended. I once saw a patient who went to climb Baiyun Mountain every day after he retired and sweated profusely every time. Once he had chest tightness after sweating a lot, he came to my night clinic and found out that he had an acute heart attack after an electrocardiogram. This patient himself had coronary heart disease, but he didn’t know it himself, as many people do. If this patient had not come to see the doctor at that time, he would have lost his life in a heart attack. A good lifestyle is important, but there must be degrees, or too much is too little. Patients with coronary heart disease, in addition to measuring blood pressure, to know their heart rate, their own pulse can be counted, the morning pulse does not exceed 70 times, in the 60 times is the best. However, patients with severe arrhythmias cannot use this method. For example, in patients with atrial fibrillation and arrhythmia, the method of counting the pulse by yourself is not accurate. Heart rate too slow is also not good Coronary heart disease patients have a relatively large myocardial oxygen consumption, which will aggravate myocardial ischemia, so you can take some methods such as guidance and qigong to slow down the heart rate, and then use beta-blockers to assist the treatment, so that the heart can better long-term operation. Of course, a heart rate that is too slow will not work either. The human body is like a car, there has to be an appropriate degree of speed and engine to make the car run better. We talk about life is in motion, life is in activity, life is in peristalsis, life is in immobility, all these statements are true, but for different people, it is different from person to person, the key is to see which lifestyle is suitable for your situation. Do your own angina record One patient did a good job, he would record the number of times he had angina for me to see every time he came to the doctor. For example, whether the number of times is more or less, which time of day is more painful, pain when climbing stairs or pain when mood swings, all recorded. This is a good analysis for myself, and also provides a good basis for doctors. Nowadays, in the management of chronic diseases, such as coronary heart disease, diabetes, hypertension, stroke, etc., patients basically have to do their own daily monitoring. Nowadays, there are many self-monitoring devices, through which patients can monitor their blood glucose, blood lipids and blood pressure at any time, and upload the data, so that doctors can help analyze them, which is also a trend of self-monitoring for patients in the future.
