Supraventricular tachycardia (SVT)

Also known as Atrial Tachycardia

Supraventricular tachycardia includes many forms of arrhythmia (irregular heartbeat) originating above the ventricles. SVT can cause the heart to beat very rapidly or erratically. As a result, the heart may not pump efficiently enough to deliver an adequate blood supply to the body. There are three major types of SVT:

  • Atrial fibrillation – Atrial fibrillation is a type of cardiac arrhythmia (heart rate and or rhythm abnormality). Atrial fibrillation produces a rapid and irregular heartbeat, during which the atria (the upper two chambers of the heart that receive blood) quiver, or fibrillate, instead of beating normally.
  • Paroxsymal Supraventricular tachycardia (PSVT) – This “short circuit” arrhythmia is commonly mistaken for a panic attack. It is generally not dangerous and can be treated with medications or catheter ablation.
  • Atrial flutter and atrial tachycardia – This arrhythmia is characterized by a fast heart rate (more than 100 beats per minute) that starts in the upper chambers of the heart. Atrial flutter is episodic, meaning it arises for a few minutes a day and suddenly disappears.
