摘要
目的:探讨12导联同步动态心电图在室性期前收缩定位中的意义。方法:对120例频发室性期前收缩患者的QRS波群形态进行分析定位。结果:120例中40例行射频消融术,术中定位为右室流出道者36例,符合率97.30%(36/37),左室流出道者3例,符合率100%(3/3)。结论:12导联同步动态心电图监测在室性期前收缩定位中的准确性较高,可用于室性期收缩射频消融术前的常规检查。
Objective： To study the significance of 12 leads ambulatory electrocardiogram （AECG） in fixing of ventricular premature beat （VPB） . Methods： The data of 120 patients with frequency VPB were analyzed according fixing in AECD. Results： There were 36 patients （97.3%, 36/37） diagnosed as fixing in right ventricular outflow tract （RVOT） and 3 patients （100%, 3/3） were diagnosed as fixing in left ventricular outflow （LVOT） in 40 patients with radiofrequency current catheter ablation （RFCA）. Conclusion： The 12 leads AECG can be used as general examination before RFCA because its high accuracy in fixing of VPB.
