Patients with atrial fibrillation can not be generalized whether it is better to exercise regularly or to be sedentary. If there is no thrombosis in the atria of the heart, no cardiac insufficiency and other conditions, it is recommended to exercise appropriately, and on the contrary, it is necessary to be sedentary. 1. Recommended appropriate exercise: atrial fibrillation main risks are heart failure and the occurrence of embolism. If there is no thrombus formation in the atrium of the heart, no cardiac insufficiency and other conditions, the occurrence of cardiac insufficiency and embolism after exercise is relatively small, and it is recommended that the patient carry out moderate aerobic exercise, such as brisk walking, jogging, swimming, etc., to increase blood circulation, improve the blood supply to the myocardium, and increase the reserve capacity of the heart, which will help to improve the cardiac function of atrial fibrillation. 2. It is recommended to take rest and recuperation: atrial fibrillation patients, due to the irregular contraction of the heart, can cause the blood clotting substances to gather in the atrium and form thrombus in the atrium. Exercise may cause dislodgement of thrombus, and the embolus, along with blood circulation, may block the brain, kidneys and other important organs, causing acute embolic events and aggravating heart failure, which may be life-threatening. Therefore, sedation should be the main focus. Patients with atrial fibrillation should also be treated with medications under the guidance of a doctor, such as anticoagulant medications such as warfarin, rivaroxaban, and dabigatran etexilate, ventricular rate controlling medications such as metoprolol, bisoprolol, and cardiac glycosides such as digoxin, etc., with regular follow up and timely treatment for any discomforts.
