Long QT Syndrome. Electrocardiogram of Dangerous Drug Interactions

pp 491-494

Abstract

Ventricular repolarization is not always evaluated properly at the moment of adopting certain medical management and its consequences might be fatal. Electrolyte disturbances and class III antiarrhythmic drug therapies are frequent associations in daily clinical practice and constitute two factors that have great repercussions as they may modify ventricular repolarization and generate malignant ventricular arrhythmias. This case report deals with drug interactions, electrocardiographic changes and proarrhythmic effects.
