What is SVT?

Supraventricular tachycardia (SVT) is a general name for arrhythmias that start above the ventricles. It is sometimes called paroxysmal supraventricular tachycardia (PSVT) because it occurs intermittently, or from time to time.

SVTs usually begin and end suddenly, and can last anywhere from seconds to hours. They may cause the heart to beat 160-200 times a minute.

Can SVT Be Treated?

SVTs are generally not life-threatening, unless the patient has another heart problem. Symptoms can vary in severity, and the more severe forms may require treatment with medications or catheter SVT ablation.
