摘要

Understanding the cardiac risks of antipsychotic use is crucial for clinicians managing psychiatric conditions in children and adolescents. However, the effects on the QT interval in pediatric populations have been poorly investigated. We performed a systematic review to provide clinicians an updated source on the effects of antipsychotic medications on QTc and guide drug’s choice. A literature search on the PubMed and Scopus databases was conducted from April 22, 1989, to May 28, 2023, for all studies investigating the effects of antipsychotic medications on the QTc interval in patients aged 0–18 years. A total of 10 articles including 523 patients and 7 different antipsychotic drugs met our search criteria. Among the included articles were three randomized clinical trials, five controlled trials without randomization or prospective comparative cohort trials, and two retrospective cohort studies. Clinical data emerging from these studies were classified according to the Oxford Centre for Evidence-Based Medicine. Risperidone and aripiprazole showed minimal to no significant QTc prolongation, whereas quetiapine, olanzapine, and ziprasidone showed variable effects on QTc. Haloperidol did not demonstrate significant QTc prolongation. In a prospective comparative cohort trial, pimozide exhibited significant QTc prolongation in a cohort with Tourette syndrome.

Conclusion: Only 10 studies have carefully addressed the effect of antipsychotic medications on QTc among pediatric patients, underscoring the need for further research. Personalized risk assessment and regular cardiac monitoring should be integrated into clinical management of pediatric and adolescent patients receiving antipsychotics to facilitate early detection of repolarization abnormalities and potential intervention.

What is known:

• QT interval prolongation is a reported side effect of antipsychotics among adults especially with first-generation antipsychotics and parenteral infusion.

• Understanding the effect of antipsychotics on QT is essential for clinical monitoring and avoidance of complications.

What is new:

• Risperidone and aripiprazole were the most studied antipsychotics in pediatric patients and showed minimal QT prolongation.

• The absence of a standardized protocol for assessing the effects on the QT interval makes comparisons between studies challenging and emphasizes the need for further research.
