A patient is described with the clinical syndrome of "swallowing syncope" who reproducibly demonstrated sinus bradycardia, A-H prolongation, and intranodal atrioventricular block in response to swallowing during electrophysiologic study. Baseline electrophysiologic and esophageal manometric results were normal, as was his response to other vagal maneuvers. Demand ventricular pacing alleviated his symptoms. These findings suggest that "swallowing syncope" is mediated via an esophageocardiac reflex and can occur in the absence of cardiac conduction system or esophageal disease.
本文描述了一名患有“吞咽性晕厥”临床综合征的患者，在电生理研究中，其吞咽时可重复性地出现窦性心动过缓、A-H间期延长和结内房室传导阻滞。基线电生理和食管测压结果正常，其对其他迷走神经动作的反应也正常。按需心室起搏可缓解其症状。这些发现表明，“吞咽性晕厥”是通过食管心脏反射介导的，且可在无心脏传导系统或食管疾病的情况下发生。
