When should ECG monitoring occur for antipsychotic medications?

ECG monitoring for patients on antipsychotic medications is primarily important due to the potential risk of QT interval prolongation associated with some of these drugs. This monitoring becomes particularly critical when there is a change in dosage as it can impact the cardiac effects of the medication.

When a patient starts a new antipsychotic or when there is a dose adjustment, an ECG is necessary to establish a baseline and to detect any dangerous alterations in heart rhythm that might occur as the dosage is increased or decreased. Regular monitoring, ideally done annually, allows clinicians to identify any late-onset side effects related to cardiac function and provides a safeguard against serious complications.

This frequency helps ensure that any emerging cardiovascular issues can be addressed promptly, allowing for timely adjustments to therapy if needed. Thus, the recommendation for monitoring after dose changes and ideally once a year represents best practice in managing both the therapeutic and potential adverse effects associated with antipsychotic treatments.
