What is supraventricular tachycardia (SVT)?

ANSWER

If you’ve felt a rapidly beating heart out of the blue, you might have checked into it and come across the term “supraventricular tachycardia,” or SVT. It's a group of several different heart conditions. Most of the time, SVT doesn't cause any serious health problems. But be sure to make an appointment with your doctor if you’ve felt your heart racing when you haven’t been exercising or feeling anxious.
