Asystole and bradycardia during maxillofacial surgery.
A Chinese female undergoing maxillary osteotomy developed asystole when the maxillary tuberosity was cut. Surgery was stopped. After about 10 sec and before instituting cardiac massage, sinus rhythm and bradycardia ensued. Atropine was administered intravenously, resulting in an increase in heart rate. No further episodes of asystole or bradycardia were encountered.
