[The cardiotropic effect of antidepressants in aging patients (author's transl)]

This quinidine-like effect prolongs the QT-interval of ECG and can induce reentry and ventricular fibrillation. When quinidine and antidepressants are combined in the same patient the risk of such cardiac complications increases.
