There are more causes of arrhythmia, some of which can be cured or self-healed, while the other part is not curable, mostly seen in arrhythmia caused by various pathologic factors. 1. Curable or self-healing: arrhythmia is caused by congenital heart disease or pseudotendonitis, etc., which can be cured completely through surgery. Arrhythmia occurs after emotional excitement or strenuous exercise, and the symptoms can be relieved after resting and stabilizing the emotions, and does not need any special treatment. 2. Uncurable: Coronary heart disease and insufficient blood supply to the heart muscle can cause arrhythmia, which can be treated with medicines that nourish the heart muscle and improve the blood supply to the heart, such as isosorbide mononitrate tablets and antiarrhythmic medicines such as metoprolol tartrate, etc. However, in general, with the above treatments, the arrhythmia can be completely cured by surgery. However, in general, the above treatments can only improve the symptoms of arrhythmia, but not completely cure and easy to recur. Although most patients with pathological arrhythmia cannot be completely cured, they can achieve a relatively stable state through oral medication, so it is important to follow the doctor’s advice and take medication regularly.
