Whether arrhythmias can exercise is determined by the underlying disease, severity, and nature of the condition, as follows: 1. Most patients with arrhythmias can exercise, such as premature beats and atrial fibrillation; 2. Patients with acute and malignant arrhythmias cannot exercise; for example, the heart rate reaches more than 200 times during episodes of supraventricular tachycardia, and patients are dizzy and weak, which is not suitable for exercise; frequent premature ventricular beats and repeated periods of ventricular tachycardia are also not suitable for exercise; 3. Patients with stable atrial fibrillation advocate moderate exercise. Patients with arrhythmias should usually develop good lifestyle habits.
