Torsade de pointes is a form of polymorphic ventricular tachycardia associated with heart rate–corrected QT (QT_c) interval prolongation. With approximately 24–61% of critically ill patients experiencing QT_c interval prolongation, a predictive tool to identify high‐risk patients could assist in the monitoring and management in the intensive care unit (ICU). The Tisdale et al. Risk Score (TRS) is a predictive tool that was developed and validated in a cardiac critical care unit.
