Acute Atrial Fibrillation Induced by Organophosphorus Poisoning: Case Report

Mahmoud Hassan Abdelnaby

Organophosphorus poisoning (OPP) remains a major clinical and public health problem in developing countries. OP compounds act as irreversible cholinesterase inhibitors. Toxicity of these compounds leads to cholinergic excess symptoms through the muscarinic, nicotinic, and central nervous system receptors . Cardiac complications include cardiac arrest, pulmonary oedema, and arrhythmia. Rarely, myocardial infarction has also been reported. Cardiac injury is a strong predictor of death in these patients . We are reporting a case of OP poisoning in a child recently admitted to our facility with acute onset of atrial fibrillation which reverted to sinus rhythm by direct current (DC) cardio version and detoxification of OP component.
