Abstract: Catecholaminergic polymorphic ventricular tachycardia (CPVT), also called exercise-induced ventricular tachycardia is a hereditary disease that can cause sudden cardiac death in Websympathetic activation.5 Eventually, the adverse conse-quences of this neurohumoral activation will dominate over the short-term compensatory effects (compensation of a diminished heart function by increase of cardiac rate and contractility, vascular tone, venous return, and circula-tory filling). They are mediated through downregulation of
