Nodal rhythm and ventricular parasystole: an unusual electrocardiographic presentation of mad honey poisoning.

Mad honey poisoning syndrome has been reported in the Eastern Black Sea region and Southeastern regions of Turkey. Herein we report a case of 70-y-old man presented with syncope and severe hemodynamic instability following ingestion of one teaspoon of honey and his unusual electrocardiographic manifestations: nodal rhythm alternating with sinus bradycardia and intermittant ventricular parasystole. In this report, we also tried to explain the possible mechanism responsible for these electrocardiographic findings.
