Two cases of torsade de pointes associated with bradycardia and takotsubo cardiomyopathy are reported. In both cases, atrioventricular block preceded the occurrence of takotsubo cardiomyopathy. Bradycardia-induced QT interval prolongation seemed to be amplified by the occurrence of takotsubo cardiomyopathy, resulting in torsade de pointes. Temporary ventricular pacing at a high rate decreased the QT interval and prevented the recurrence of torsade de pointes. Because atrioventricular block recurred or persisted even after the resolution of takotsubo cardiomyopathy, the patients received permanent pacemakers.
