Two years ago, my heart was beating too fast for about 4 minutes, and it happened many times. After examination, the doctor said it was supraventricular tachycardia, without any treatment. Can supraventricular tachycardia be reduced? Can it be done without surgery? What is the best way? Supraventricular tachycardia is a congenital tachycardia caused by a double atrioventricular node pathway or atrioventricular bypass. The onset of symptoms is sudden and can last for minutes or tens of hours. In many patients, tachycardia can be stopped by holding one’s breath, picking one’s throat, or inducing nausea and vomiting. If the patient is relatively young, or if the symptoms are mild, have few episodes, last for a short period of time, do not affect work life, and do not cause syncope or blackout, then the patient can be observed. Otherwise, radiofrequency ablation can be performed. This is a minimally invasive procedure with good results and quick recovery, and you can go home the day after the procedure. Your case can continue to be observed.
