预激综合征可伴有严重心律失常,轻者需终生服药,重者丧失劳力,甚至死亡。我们对1例A型预激综合征成功地进行心内膜与心外膜标测,确定了旁道(副传导束)部位,并手术切断。报道如下。 患者,男,34岁,因心动过速10余年,曾多次发作晕厥,于1990年12月4日入院求治。常规心电图检查呈A型预激综合征(图1)。食道电生理 Wolff-Parkinson-White syndrome may be accompanied by severe arrhythmia, light need to take medication for life, severe cases of loss of labor, and even death. We performed a successful endocardial and epicardial mapping of one case of type A pre-excitation syndrome, identified the accessory tract (accessory conduction bundle) site, and severed the operation. Reported as follows. Patient, male, 34 years old, had multiple episodes of syncope due to tachycardia for more than 10 years and was admitted to hospital on December 4, 1990. Conventional ECG was type A WPW syndrome (Figure 1). Esophageal electrophysiology
