Letters to the Editor QTc Prolongation: Chlorpromazine and High-Dosage Olanzapine

The electrocardiographic QT interval reflects ventricular depolarization (QRS complex) and repolarization (ST segment and T wave). It varies inversely with heart rate and is usually less than or equal to one-half the RR duration (1). The heart rate corrected interval (QTc) is normally less than or equal to 440 ms, and a QTc of over 500 ms characterizes an increased risk for developing dangerous...
