Catecholaminergic polymorphic ventricular tachycardia

Catecholaminergic polymorphic ventricular tachycardia (CPVT), also called familial polymorphic ventricular tachycardia (FPVT) or catecholamine-induced polymorphic ventricular tachycardia, is a disorder characterized by an abnormal heart rhythm (arrhythmia). Thought to affect as many as one in ten thousand people, it is estimated to cause 15% of all unexplained sudden cardiac deaths in young people.
