Neurocardiogenic syncope due to recurrent tonsillar carcinoma: successful treatment by dual chamber cardiac pacing with rate hysteresis.
A patient with recurrent tonsillar carcinoma in his neck presented with cardioinhibitory neurocardiogenic syncope. Ventricular demand pacing was ineffective in preventing recurrent symptoms. The pacemaker was upgraded to a dual chamber device with hysteresis that eliminated further syncopal episodes.
