Catecholamine-sensitive right ventricular tachycardia in the absence of structural heart disease: a mechanism of exercise-induced cardiac arrest.
A case of exercise-induced cardiac arrest secondary to catecholamine-sensitive right ventricular tachycardia in the absence of apparent structural heart disease is presented. Amiodarone therapy prevented tachycardia induction, symptoms and clinical events despite a return to vigorous exercise.
