Ventricular Tachycardia (VT)

Ventricular tachycardia (VT) is a rapid, regular heart rate that originates with abnormal electrical signals in the ventricles (lower chambers of the heart). The fast heart beats can occur in short bursts, or they may last longer than 30 seconds. VT is a serious arrhythmia that can cause a sudden fall in blood pressure and may cause loss of consciousness known as syncope (fainting). Without prompt medical treatment, ventricular tachycardia may worsen into ventricular fibrillation and cardiac arrest.
