Synonyms: Familial Polymorphic Ventricular Tachycardia (FPVT), Catecholamine-Induced Polymorphic Ventricular Tachycardia. 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.First recognized in 1975, this condition is due to mutations in genes encoding a voltage gated calcium channel or proteins related to this channel. All mutated proteins participate in the regulation of calcium ion flow in and out of the sarcoplasmatic reticulum of cardiac cells. Therefore reduced electrical stability of cardiomyocytes may cause the heart to enter a life threatening state of ventricular arrhythmia as response to the natural release of catecholamines from nerve endings on the heart muscle and from the adrenal glands into the circulation. This rhythm disturbance prevents the heart from pumping blood appropriately. Ventricular tachycardia may self-terminate or degenerate into ventricular fibrillation, causing sudden death unless immediate cardiopulmonary resuscitation is applied.. }
