Torsades de Pointes in Takotsubo Cardiomyopathy with QT Prolongation

Transient Long QT Development in a Patient with Takotsubo Cardiomyopathy

“…12-lead electrocardiograms recorded on admission (A), at 1 hour (B) and on the second day (C).higher propensity to malignant ventricular arrhythmias, these are relatively uncommon in TCM patients, with an incidence of only 1-1.5% 1. In a number of case reports on TCM-associated long QT and consequent torsades de pointes arrhythmia, the QT prolongation was attributed to electrolyte disturbances, bradyarrhythmia or enhanced lability of repolarization 5. Therefore the risk of long QTrelated tachyarrhythmias may be successfully reduced by avoiding these proarrhythmic conditions via continuous monitoring, appropriate electrolyte supplementation or transvenous pacing 3,6.…”
