title: Midventricular ballooning Takotsubo cardiomyopathy complicated by transient complete atrioventricular block.
abstract: A 63-year-old woman had mistakenly drunk detergent stored in a plastic bottle and was transported to our hospital via ambulance due to unconsciousness. In the emergency room, the monitoring electrocardiogram showed complete atrioventricular block and temporary pacing was thus started. Left ventriculography indicated midventricular Takotsubo cardiomyopathy, although coronary angiograms showed a normal appearance. The atrioventricular block was transient, and the reduced left ventricular wall motion gradually recovered. An electrophysiological study performed before discharge showed no abnormalities in the atrioventricular conduction system. In conclusion, we experienced a case of mid-ventricular Takotsubo cardiomyopathy complicated by transient complete atrioventricular block.
