Our experienced electrophysiology team treats the full spectrum of arrhythmias, including paroxysmal supraventricular tachycardia (PSVT).

PSVT is an arrhythmia marked by sporadic periods of rapid heart rate that begin and end suddenly. It starts in the heart’s top chambers (atria).

While PSVT usually does not threaten your life if you have it, it can lead to congestive heart failure or angina if you have other heart problems.

PSVT Causes

PSVT is caused by extra electrical pathways between the heart’s upper chambers (atria) and lower chambers (ventricles). There are several factors that can increase your risk for developing the condition:

  • Certain heart medications
  • Alcohol
  • Caffeine
  • Smoking
  • Recreational drugs
