Ventricular tachyarrhythmias are a group of arrhythmias that result in a heartbeat greater than 100 beats per minute and originate anywhere in the ventricle. There are three main types of ventricular tachyarrhythmias: ventricular fibrillation, monomorphic ventricular tachycardia, and polymorphic ventricular tachycardia. Each one is associated with a high mortality rate. Symptoms include chest pain, palpations, hemodynamic collapse, and end-organ damage.
