First, diet and health.
Patients with atrial fibrillation must have regular eating habits. They can usually eat more vegetables and fruits. Fresh fruits and vegetables are rich in vitamins and cellulose, and also contain more potassium, because these foods help to control blood pressure and maintain electrolyte balance. So prevent the occurrence of atrial fibrillation. We should also develop a good habit of not smoking or drinking, and drink less stimulating drinks such as coffee and strong tea. Do not eat or eat less spicy food, such as curry, pepper, onion, garlic, etc.
Second, keep a good mood.
No matter what illness you have, I think the most important thing is to keep a good mood, because only when you are in a good mood will the illness not be so serious. Moreover, people with heart disease can't get excited at all, because after excitement, the load on the heart will increase, which will lead to heart disease. So you must keep a good mood at ordinary times.
Third, reasonable exercise.
Although people with heart disease can't do strenuous exercise, because it will increase the load on the heart. But we can usually do some light physical exercise, such as walking, walking slowly, playing Tai Chi and so on. These can be good exercises, but you still need to choose the exercise mode that suits you according to your physical condition. Don't force yourself, it can enhance the body's resistance.
These are my opinions, and you are welcome to add them.
