Three patients undergoing surgery for cerebello-pontine angle meningioma suffered transient episodes of asystole. All patients exhibited return to the previous heart rate with cessation of surgical manipulations and administration of anticholinergic agents. These reactions were apparently elicited by activation of the trigeminocardiac reflex (TCR) by direct stimulation of the trigeminal nerve or branches in the dura mater or cerebellar tentorium.
