Supraventricular Tachycardia

Supraventricular tachycardia (SVT) is a very fast heartbeat that happens from time to time because of a problem with your heart's electrical system. It may make you feel like your heart is racing, pounding, or out of rhythm. It usually isn't life-threatening, but you may need treatment.
