title: Case report: an unusual heart rhythm associated with organophosphate poisoning.
abstract: Organophosphate pesticides have emerged as a common cause of poisoning, particularly in developing countries. The most common electrocardiographic abnormalities observed in organophosphate poisoning are sinus tachycardia, QT interval prolongation, and, very rarely, ventricular arrhythmias. We report a case of organophosphate poisoning associated with atrial fibrillation, right bundle branch block, QT interval prolongation, and intermittent narrow QRS complexes that were most likely due to automaticity from the region of the left posterior fascicle.
