Also known as: Monomorphic ventricular tachycardia; Polymorphic ventricular tachycardia
Ventricular tachycardia is a fast heart rhythm that starts in the lower part of the heart (ventricles). If left untreated, some forms of ventricular tachycardia may get worse and lead to ventricular fibrillation, which can be life-threatening.
Ventricular tachycardia is a fast but regular rhythm. It can lead to ventricular fibrillation which is fast and irregular. With ventricular fibrillation, the heart beats are so fast and irregular that the heart stops pumping blood. Ventricular fibrillation is a leading cause of sudden cardiac death.
