[A taste of honey : Rare cause of syncope associated with junctional rhythm].

We present a rare reversible cause of bradycardia. A 49-year-old man who suffered from syncope was administered to our emergency department. In preclinical ECG recordings, a sinus node arrest was documented. All following examinations documented normal sinus node function. Finally, grayanotoxin poisoning, which can be present in honey from the Black Sea region, was proven. A pacemaker implantation could be avoided in this reversible cause of bradyarrhythmia.
