There is no accurate answer to the question of how long the arrhythmia can be cured. Physiological factors are usually cured within 1 week, and pathological factors can be cured by surgery or long-term medication, but there is no specific time statistics, and some of them may not be cured. 1. Physiological factors: some patients may have arrhythmia caused by physiological reasons, such as emotional excitement, poor sleep, drinking alcohol, strong tea, coffee, sinus tachycardia, atrial premature beats, ventricular premature beats and other arrhythmias, the elimination of the above factors is generally cured in less than 1 week. 2. Pathologic factors Some patients with arrhythmia can be treated surgically, such as paroxysmal supraventricular tachycardia, focal atrial tachycardia, preexcitation syndrome, etc. After catheter ablation, the arrhythmia can be cured in a short time during the operation. Some patients with arrhythmia, which may be caused by other diseases, such as hyperthyroidism, need long-term propylthiouracil, methimazole and other medications, the cause of the disease can be eliminated to cure, but there is no specific time statistics. Some patients may be due to congenital developmental abnormalities, or the condition is more serious, or the cause persists and is difficult to eliminate, such as Brugada syndrome caused by ion channelopathies, ventricular tachycardia caused by dilated cardiomyopathies, etc., which is generally difficult to cure. If you suffer from arrhythmia, it is recommended to go to the hospital as soon as possible to improve the electrocardiogram and cardiac ultrasound and other auxiliary examinations, with the help of the doctor to comprehensively analyze the condition, and to carry out targeted treatment.
