ECG monitoring should be considered in all patients prescribed antipsychotics before and after starting treatment to avert the risk of sudden cardiac death and ventricular arrhythmias, say Australian doctors.

The advice follows new findings by Taiwanese researchers that about one in eight adults taking quetiapine or haloperidol will develop severe QT prolongation (SQTP).
