Failure of Intracardiac Pacing After Fatal Propafenone Overdose: A Case Report

Abstract Background Propafenone is a sodium-channel blocker, class IC antiarrhythmic drug, frequently used to manage supraventricular dysrhythmias, especially atrial fibrillation. We report a self mono-intoxication with propafenone. Case Report A 68-year-old woman presented with a decreased level of consciousness, hypotension, and electrocardiogram showing QRS widening with atrial asystole and extreme bradycardia Why Should an Emergency Physician Be Aware of This? Emergency physicians should be aware of possible propafenone ingestion causing toxicity, which is probably more frequent than previously described, especially because propafenone is widely available due to its use in managing atrial fibrillation, the most common arrhythmia nowadays.
