Supraventricular tachycardia (SVT) carries certain risks for affected patients. If the arrhythmia persists and fails to revert spontaneously, the excessively rapid heart rate may precipitate heart failure. Patients should maintain adequate rest, avoid physical overexertion, and prevent mental stress or anxiety—particularly sudden emotional fluctuations—as these measures can help reduce the frequency of acute episodes. For patients experiencing frequent or recurrent episodes, referral to a cardiologist is warranted; in some cases, radiofrequency catheter ablation may be indicated.
