Electrocardiograms (ECGs) from a case series of 86 amisulpride overdose events in 66 patients were reviewed for abnormal QT intervals and torsade de pointes (TdP). Eight patients exhibited TdP. In this investigative case series, the magnitude of prolongation of the QT interval was a stronger predictor of TdP than the mere presence of a prolongation per se.
