Case Reports: An unusual clinical state: atrial fibrillation due to mad-honey intoxication

The honey which is produced in the Karadeniz Region of Turkey and known as the ``mad honey`` contains Rhododendron ponticum nectar. Grayanotoxin is only produced by Ericaceae plants and thought to be responsible for toxicity. The typical symptoms are gastrointestinal and may sometimes cause cardiac complications, such as severe bradycardia and hypotension. In our case, we report a patient with unusual cardiac toxicity symptom such as atrial fibrillation, following ``mad honey`` ingestion and give a review of clinical presentation and treatment of grayanotoxin poisoning.
