Takotsubo Cardiomyopathy (TCMP), also known as apical ballooning syndrome or stress induced cardiomyopathy, is characterized by left ventricular mid and/or apical wall motion abnormality in the absence of obstructive coronary artery disease. TCMP is a disorder of left ventricular myocardial contractility, and rarely associated with serious cardiac conduction abnormalities. We reported a case of 80-year-old female who developed transient AV block, bradycardia and ventricular tachycardia in presence of long QT associated with TCMP, which was treated temporary venous pacing. After 3 months of follow up, she remained symptoms free and LVEF was normalized on repeat echocardiogram. TCMP can be considered a transient insult on myocardial repolarization caused by autonomic function disturbances and it causes TdP in presence of predisposing factors such as cardiac conduction anomalies, bradycardia, metabolic disease, medications, and genotype abnormalities. Research is warranted to examine outcome of TCMP patients with prolonged QTc interval.
