Recurrent Ventricular Tachycardia in Hypothyroidism

Abstract

Ventricular tachycardia associated with myxoedema is rare. Only two cases have so far been documented. In the report by Hansen, the patient had recurrent chest pain which suggested coexisting coronary heart disease. In the second case, the patient developed recurrent ventricular tachycardia only after intravenous triiodothyronine was given. This paper reports a further case of hypothyroidism with recurrent episodes of ventricular tachycardia and ventricular fibrillation which was not associated with any of the established causes of this arrhythmia.
