The Effect of Antipsychotics and Their Combinations with Other Psychotropic Drugs on Electrocardiogram Intervals Other Than QTc among Jordanian Adult Outpatients.

The ECG changes produced by antipsychotics and other psychotropic medications are studied mostly regarding QTc interval prolongation. This study aimed to investigate ECG changes beyond long QTc interval produced by psychotropic medications. A cross-sectional study was conducted to assess the effect of these agents on RR, PR, TpTe intervals and TpTe/QT ratio among Jordanian outpatients.

The Effect of Psychotropic Medications and Their Combinations on the QTc Interval Among Jordanian Outpatients: A Cross-Sectional Study.

Objective: To investigate the effect of psychotropic drugs and their combinations on the QTc interval as well as the prevalence of long QTc (LQTc) among ambulatory patients with psychiatric illness in Jordan.

Methods: A cross-sectional study that included patients treated in an outpatient psychiatric clinic was conducted. The QTc duration was calculated using a combined QT correction (Bazett's formula for heart rate 60-100 and the Framingham formula for extremes of HR).
