title: Oculocardiac reflex induced by zygomatic fracture; a case report.
abstract: Oculocardiac reflex has been recognized as the result of mechanical stimulation to the orbital tissue. The authors encountered a case of severe arrhythmia due to oculocardiac reflex in a patient with a zygomatic fracture. Previous health examinations suggested no abnormalities in the heart in his schooldays, and the initial diagnosis of his arrhythmia as complete A-V block due to injury (using ECG and cardiac ultrasonography). Because his arrhythmia did not improve spontaneously, he underwent cardiac pacing. After repair of the fracture, his arrhythmia completely disappeared. The pacemaker was removed on the first postoperative day. The pathogenesis of this rare case will be discussed.
