AIMS AND METHOD
The risk of developing fatal tachyarrhythmias can increase in patients receiving antipsychotic medication. Two surveys were conducted, one to evaluate junior doctors knowledge of the QTc interval and the second to investigate the experience of electrocardiographic (ECG) monitoring among patients on four acute psychiatric wards.
RESULTS
The first survey revealed that junior doctors were lacking in knowledge regarding the QTc interval. The second revealed that ECG monitoring of high-risk patients was inadequate. Half of the high-risk patients who required an ECG were not given one, whereas 6% who did not require one still received this investigation.
CLINICAL IMPLICATIONS
There is a need to increase knowledge about the cardiac risk of antipsychotic medication on psychiatric wards. Following simple recommendations could improve clinical practice.
