As the saying goes, “life is exercise”, the benefits of exercise are numerous, not only for the growth of human bones and muscles, but also to enhance cardiopulmonary function, improve immunity and strengthen the body. But the heart of patients with arrhythmia, compared to healthy people “fragile”, so these little hearts can still enjoy the “benefits” of exercise? In fact, there are many kinds of sports, not all of them are “insulated” from arrhythmia patients. On the contrary, patients with arrhythmias who choose the right exercises can not only achieve the purpose of strengthening their bodies, but also protect their heart function more. Moderate exercise can improve the body’s nerves and blood circulation, speed up the heart rate, strengthen the heart’s conduction function, and increase the myocardial collateral circulation to improve the blood supply to the heart muscle. So what exercises should arrhythmia patients choose? Patients with arrhythmias should choose moderate intensity, milder exercises, such as jogging, walking, taijiquan, eight-danjin, health exercises, and so on. The rest of the more strenuous sports such as fast running, taekwondo, basketball, soccer, etc., can only say “bye” to them with tears, because strenuous activities greatly increase the burden on the heart, beyond the load on the heart, can further deteriorate the function of the heart, leading to heart failure, and can cause death in serious cases. However, the choice of the type of exercise should be based on the severity of the patient’s own arrhythmia, and we recommend that you choose a suitable exercise for yourself after discussing with your doctor. If you feel chest tightness, shortness of breath, dizziness, etc., you should stop exercising immediately and rest for a few moments to wait for the symptoms to subside, or if the symptoms are severe, you should seek medical attention as soon as possible. However, patients with sinus bradycardia, atrioventricular block, or tachyarrhythmia attacks, along with dizziness, blackness, or even syncope, may have a lighter amount of exercise become “too heavy for their lives”. Our advice to these patients is to prohibit all sports and exercise and seek medical attention as soon as possible. In conclusion, whether you are a healthy person or a patient with arrhythmia, we hope that you will choose the right form of exercise for you and stick to it for a long time to prevent the occurrence of diseases and to improve the quality of our lives.
