When Normal Electrical Activity Is Interrupted (2 of 2)

• Ventricular tachycardia (V-tach)
  • A common abnormal heart rhythm in cases of sudden cardiac arrest in adults
  • Very rapid electrical activity
  • Heart may be unable to pump blood effectively.

Ventricular tachycardia (V-tach or VT) is a type of tachycardia, or a rapid heart beat that arises from improper electrical activity of the heart presenting as a rapid heart rhythm, that starts in the bottom chambers of the heart, called the ventricles.

The ventricles are the main pumping chambers of the heart. This is a potentially life-threatening arrhythmia because it may lead to ventricular fibrillation, asystole, and sudden death.
