Bradycardia caused by the oculocardiac reflex is an anticipated occurrence during certain surgeries. The afferent pathway involves the trigeminal nerve's ophthalmic division. Reflex bradycardia from the trigeminocardiac reflex, via stimulation of maxillary or mandibular divisions of cranial nerve V, although less well known, has also been reported intraoperatively. Unstable bradycardia associated with stimulation of the mandibular division of cranial nerve V during trigeminal neuralgia pain episodes in the Postanesthesia Care Unit is presented.
