摘要
一例１１岁矫正性大动脉转位（ＳＬＬ）的女性患儿有晕厥史１０年，超声心动图证实心内无分流，动态心电图及电生理检查均证实为Ⅲ度房室阻滞，窦房结功能正常。安置ＶＤＤ生理性起搏器，感知与起搏电极间距为１３ｃｍ，Ｐ波振幅２．２ｍＶ、心房感知０．７５ｍＶ、心室起搏阈值０．４Ｖ。术后观察心房感知率９８％。给心内无分流的心脏畸形患儿安置起搏器要充分考虑生理和生长发育的需要，如合理选择起搏器类型和电极长度，进行电生理检查测定心尖至高位右房的距离，同时熟悉复杂心脏畸形影像学的知识对保证安置术的成功十分必要。
A 11yearold schoolgirl with the complete atrioventricular(AV) block and corrected transposition of great arteries was successfully treated with single lead VDD pacemaker.She had suffered chronic fatigue,reccurrent syncope,bradycardia for 10 years.Echocardiography confirmed the diagnosis showing no intracardia shunt.Complete AV block was evaluated by 24hour ambulatory electrocardiogram and electrophysiological study.The 13 cm singlepass VDD lead was chosen according to intracardia electrodes distance between sensing and pacing.Atrial sensitivity was 075 mV,and ventricular pacing threshold was 04 V.The percentage of P wave sensing was 98%.Conclusion:In order to make operation successful,many facts should be considered such as growing up of child,choice of pacemaker system,and Xray knowledge of complex cardiamorphology.
