Definition of Ventricular Tachycardia

Ventricular tachycardia (VT) is a cardiac arrhythmia characterized by a pulse rate of more than 100 beats per minute, with at least three irregular heartbeats in a row. The electrical signals causing this rapid beating originate in the ventricles. This is a very serious arrhythmia as it may lead to life threatening conditions such as ventricular fibrillation, asystole and sudden death.

Types of Ventricular Tachycardia

  • Monomorphic ventricular tachycardia
  • Polymorphic ventricular tachycardia
  • Torsades de pointe


Symptoms may include:
  • Chest discomfort (angina)
  • Fainting (syncope)
  • Light-headedness or dizziness
  • Palpitations
  • Shortness of breath
