Exercise, is a way of life that is respected by the general public. Some people believe that exercise is the cure for all diseases, no matter what disease, as long as you adhere to the exercise can be improved. This view is incorrect. Especially in patients with arrhythmias, not everyone is suitable for exercise, nor is any time suitable for exercise. It has been widely proven that exercise can induce arrhythmias. Because the body increases sympathetic tone during strenuous exercise, the heart rate increases, atrioventricular conduction changes, and myocardial oxygen consumption increases, thus triggering arrhythmias, especially in patients with coronary stenosis and insufficient blood supply to the heart. For patients with arrhythmias, early morning exercise is not advisable. Because early morning secretion of large amounts of catecholamines, too intense exercise will cause discomfort and induce cardiovascular diseases such as arrhythmias. For those who like to exercise in the morning, do not exercise on an empty stomach, because the concentration of free fatty acids in the blood will increase when fasting, too much free fatty acids will affect the heart muscle, which will also cause arrhythmias and other problems. So, how should arrhythmia patients exercise? The appropriateness of exercise is generally judged by subjective feelings and the time it takes for the heart rate to return to normal. Slight shortness of breath during exercise should be significantly reduced within about 4 minutes after rest, and the heart rate returns to normal or near normal; otherwise, too much exercise should be considered. Patients with cardiovascular disease or those at risk should exercise to the extent that it does not cause special discomfort. Low-volume endurance exercise of 20 to 30 minutes four to five times a week, or moderate-volume endurance exercise of more than three times a week, with each sustained engagement of 40 to 60 minutes, is appropriate. Generally speaking, heart patients with arrhythmia are suitable for exercises such as walking, jogging, tai chi and health exercises. Exercise should ensure that you feel good about yourself, not accompanied by chest tightness, chest pain, panic, shortness of breath and cough, fatigue, etc., if the above discomfort appears, then you should immediately stop the exercise. Some patients with malignant arrhythmias, such as severe sinus bradycardia, atrioventricular block, frequent episodes of ventricular tachycardia with hemodynamic effects, rapid atrial fibrillation associated with strenuous activity, and a history of sudden cardiac death, must be treated aggressively for the primary disease before appropriate activity can be performed. Otherwise, the above patients are not suitable for any level of physical activity.
