Is running beneficial for sinus arrhythmia

Whether running is beneficial for sinus arrhythmia needs to be judged based on specific circumstances. If it is physiological sinus arrhythmia and there is no organic heart disease, moderate running usually helps improve heart rhythm; If it is pathological or accompanied by other heart problems, it may worsen the symptoms. Physiological sinus arrhythmia is more common in healthy individuals, especially adolescents and long-term exercisers. Regular cardiopulmonary load during running can help regulate autonomic nervous system function and make heart rhythm more stable. Long term aerobic exercise can enhance myocardial contractility, improve blood supply to the heart, and reduce mild arrhythmia caused by respiratory or emotional fluctuations. It is recommended to choose low-intensity exercises such as jogging and interval running, avoid sudden acceleration or intense sprinting, and control the heart rate within the range of 60% -70% of the maximum heart rate during exercise. Pathological sinus arrhythmia is often associated with diseases such as myocarditis, coronary heart disease, and thyroid dysfunction. Running in such patients may induce palpitations, chest tightness, and even fainting, especially when there is dysfunction of the sinoatrial node, which can lead to tachycardia or bradycardia after exercise. For patients with combined structural heart disease, vigorous exercise can also increase the risk of malignant arrhythmia. It is necessary to first identify the cause through dynamic electrocardiogram, cardiac ultrasound, etc., and develop an exercise plan under the guidance of a doctor, and if necessary, cooperate with medication treatment. People with sinus arrhythmia should undergo a professional cardiac assessment before running and wear heart rate monitoring devices during exercise. Avoid exercising immediately on an empty stomach or after a full meal, and pay attention to replenishing electrolytes. If you experience discomfort such as dizziness and chest pain, stop exercising immediately and seek medical attention promptly. Combining low-intensity activities such as walking and Tai Chi in daily life, maintaining a regular schedule and emotional stability are equally important for regulating heart rhythm.
