Abstract:
Takotsubo cardiomyopathy (TC) is a syndrome characterized by transient left ventricular apical ballooning associated with electrocardiogram changes and mimicking acute myocardial infarction in patients without significant coronary disease on angiography. We report an unusual case of a patient who presented with TC associated with long-QT syndrome-induced ventricular tachycardia. QT interval prolongation was normalized and ventricular tachycardias were stopped within the same day with metoprolol treatment.
