Abstract
Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare malignant arrhythmia, usually diagnosed in the adolescent years. The diagnosis can typically be made by one or more of the following: a positive family history, exercise electrocardiography, ambulatory ECG monitoring and/or an intra-cardiac, electrophysiological examination. This is a case report of a patient with CPVT that was refractory to treatment with beta-blockade and an implanted automatic cardioverter defibrillator. However, after a selective serotonin re-uptake inhibitor (SSRI) was added to the therapeutic regimen, no further episodes of ventricular tachycardia occurred during the following two years.
