Supraventricular tachycardia

Skip Navigation

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. For most people who have SVT, the heart still works normally to pump blood through the body.
