SVT can be diagnosed by your doctor through a physical exam and questions about what triggers your fast or irregular heart rate. Though most episodes of SVT are caused by the heart’s electrical system, other causes include certain drugs, health conditions, surgery and familial disorders, such as Wolff-Parkinson-White syndrome. SVT can become a problem requiring treatment if it lasts a long time or causes shortness of breath or chest pain. Others have symptoms, such as palpitations, a racing heart, sweating and feeling lightheaded or dizzy. Some patients with SVT, which generally first arises in people in their teens and 20s, may have no symptoms, going in and out of the arrhythmia quickly. The heart continues to work normally, pumping blood through the body. People with SVT may go into this arrhythmia from time to time unrelated to exercise, stress or other common causes of a rapid heart rate. SVT is also known as paroxysmal supraventricular tachycardia (PSVT) or paroxysmal atrial tachycardia (PAT). ![]() When a person goes into this arrhythmia, the heart beats at least 100 beats per minute and can be as high as 300 beats per minute. ![]() Supraventricular tachycardia (SVT) is a rapid heart rate (tachycardia) usually caused when electrical impulses originating at or above the atrioventricular node, or AV node (part of the heart's electrical control system which controls rate) are out of synch.
