Supraventricular Tachycardia
What is it?
Supraventricular tachycardia (SVT), also called paroxysmal supraventricular tachycardia, is an abnormally fast heartbeat. A normal heart rate is 60 to 100 beats per minute, and a heart rate of more than 100 beats per minute is called tachycardia. This occurs when the electrical impulses that coordinate your heartbeats don't work properly.
