QT Dispersion and Rate-Corrected QT Dispersion During Electroconvulsive Therapy in Elderly Patients

Background:Electroconvulsive therapy (ECT) induces increase of QT dispersion (QTD) and the rate-corrected QTD (QTcD), which are associated with increased risk of ventricular arrhythmias and cardiovascular mortality. The effects of electrical stimulus during ECT on QTD and QTcD in elderly patients ar
