A Case Study of Severe QT Interval Prolongation Caused by Antidepressants

QT interval prolongation can be categorized into primary and secondary types according to its etiology. In this paper, we report a case of severe asymptomatic QT interval prolongation secondary to antidepressants. Regular follow-up and electrocardiogram monitoring is crucial when applying antidepressants, especially for patients without cardiac symptoms. This article presents case studies and examines existing literature on long QT syndrome to enhance the diagnosis and management of QT interval prolongation. This is especially relevant for non-psychiatric healthcare professionals who need to be attentive to the side effects of antidepressants to prevent potential adverse consequences resulting from oversight.
