What is Supraventricular Tachycardia (SVT)?
Supraventricular tachycardia, or SVT, is a heart rhythm problem. It causes the heart to beat much faster than normal. Usually, SVT starts in the upper chambers of the heart. Because of this, the heart may not pump blood as well as it should. SVT can happen suddenly and may last for a few seconds or several hours. Although it is often not life-threatening, it can be scary. Many people with SVT feel their heart racing or pounding. According to the American Heart Association, SVT is one of the most common types of abnormal heart rhythms.

SVT symptoms can vary from person to person. However, some signs are more common than others. For example, you may notice:
