Atropine-induced ventricular fibrillation: case report and review of the literature.

A bradycardic and mildly hypotensive acute myocardial infarction patient developed sinus tachycardia, ventricular tachycardia, flutter, and fibrillation following intravenous atropine. Previous case reports are reviewed and the literature regarding the advisability of this mode of therapy is discussed. In the light of conflicting opinion as to the necessity of atropine in the mildly hypotensive and bradycardic acute myocardial infarction patient, and in view of its potentially deliterious effects on ischemic myocardium, a cautious and selective application of this drug is advised.
