An unusual cause of reflex cardiovascular syncope: vagal paraganglioma

Ertan Okmen et al. Ann Noninvasive Electrocardiol. 2003 Apr.

Abstract

Vagal paraganglioma is one of the rare tumors of the neuroendocrine system. We are reporting a vagal paraganglioma case presented with uncommon features of the disease: asystole and syncope. Syncope episodes occurred 3 years before the major symptoms of the disease. Dual chamber pacemaker failed to prevent syncope attacks because of the vasodepressor component. The patient was treated successfully with en bloc removal of tumor and vagal nerve. Syncope episodes disappeared after operation.
