摘　　要：目的探讨老年快频率依赖性室房逆传性旁道的电生理特性及射频消融技巧。方法 19例患者均有阵发性心动过速病史,发作时心电图显示为窄QRS波心动过速,按常规方法进行心脏电生理检查并在心室早搏刺激下行射频消融治疗。结果 19例均可诱发房室折返性心动过速,开始出现经旁道室房逆传的刺激频率(160～200次/min)。选择稳定出现经旁道室房逆传的固定周长在心室早搏刺激下进行标测、消融,均获成功。结论快频率依赖性室房逆传性旁道可见于老年患者,其标测消融可在心室早搏刺激下进行。【Objective】 To analyze 19 elderly cases of atrioventricular accessory pathway with rapid rate dependent ventriculoatrial conduction and summarize the experience of electrophysiological study and radiofrequency catheter ablation in these cases.【Methods】 Nineteen elderly patients,who all had symptoms of paroxysmal palpitation and whose electrocardiograms recorded at the onset of tachycardia all manifested as narrow QRS complex,underwent electrophysiological study and radiofrequency catheter ablation by the routine method.【Results】 In all patients that special kind of atrioventricular accessory pathway with rapid rate dependent ventriculoatrial conduction were demonstrated to exist by electrocardiophysiological study and the atrioventricular reentrant tachycardia were induced.Targets for ablation were identified during ventricular stimulations（S1S2） with fixed circumference and a successful ablation was attained in every patient.【Conclusion】 Rapid rate dependent conduction of atrioventricular accessory pathway is existent in elderly patients,which should be paid attention to in case misdiagnosed.The radiofrequency catheter ablation in elderly patients was identified during ventricular stimulations（S1S2）.
