Patient's question:
I have always had the habit of exercising, and recently I've been feeling that my heartbeat is abnormal. I had a thorough check-up, and the doctor said it's sinus arrhythmia. Can you run a marathon with sinus arrhythmia?Doctor's answer:
Cannot be added. The treatment of sinus tachycardia is primarily aimed at eliminating triggers, such as promoting blood circulation, controlling infection, correcting anemia, stabilizing heart function, controlling hyperthyroidism, and appropriately using β-blockers when necessary. However, it should be noted that sinus tachycardia is mainly caused by physical stress. Therefore, β-blockers should not be used in large quantities without guidance to prevent excessive heart suppression.
