This report describes a patient who presented with transient central nervous system symptoms of unknown etiology with an electro-cardiogram exhibiting a narrow QRS complex and normal. P-R interval. The decision to implant a permanent VII pacemaker was made on the basis of a His bundle study that revealed significant prolongation of the HV interval. The successful clinical outcome re-emphasizes the clinical usefulness of electrophysiological investigation in patients with syncope of undetermined etiology.
本报告描述了一名患者，其出现病因不明的短暂性中枢神经系统症状，心电图显示QRS波群狭窄且P-R间期正常。基于希氏束研究显示HV间期显著延长，决定植入永久性VII起搏器。这一成功的临床结果再次强调了电生理检查在病因不明的晕厥患者中的临床实用性。
