QT (QTC) PROLONGATION AND MONITORING
QT (QTc) Prolongation and Monitoring Primer QT (QTc) Prolongation is associated with many psychotropic medications (especially Introduction to Antipsychotics) and some are linked to serious ventricular arrhythmias (e.g. - Torsades de Pointes) and sudden cardiac death. The risk of QT prolongation is likely dose-related, but the overall absolute risk is low.
