Abstract

Torsades de pointes is a form of polymorphic ventricular tachycardia due to prolonged ventricular repolarization represented by a prolonged QT interval on electrocardiogram. Common causes of QT prolongation are usually considered in the clinical setting, such as electrolyte imbalances, medication side effects, congenital syndromes. As recent research has proposed, long-term excessive alcohol use may also be a contributing factor. The effects of alcohol on the heart have been studied extensively, showing that chronic exposure leads to cellular events and structural changes in the heart that may ultimately result in adverse clinical events. This case report presents a patient with a history of chronic alcoholism that experienced torsades de pointes and sudden cardiac death during hospitalization for a severe chronic obstructive pulmonary disease exacerbation. She was given macrolide antibiotics despite a prolonged QTc on electrocardiogram with a history of prior syncopal events. While macrolide antibiotics are known to cause QTc prolongation, chronic alcohol use has also been shown to be associated with QT prolongation. Moreover, QT prolongation may be a predictor of sudden cardiac death in alcoholics. In addition to common medication class side effects, the effects of commonly abused and readily accessible substances such as alcohol, should also be taken into consideration.
