体表心电图指导床边紧急心脏起搏的临床研究

Clinical Study on Guiding of Electrocardiogram to Bedside Urgent Cardiac Pacing by Invading Electrode Catheter

目的 探讨体表心电图对标测电极导管进行床边紧急心脏起搏的指导价值。方法 40例患者均采用非X线条件下 ,以体表心电图为指导 ,经右股静脉插入电极导管行床边心脏起搏术 ,16例患者术后 1～ 15天进行了导管位置的观察 ,对比研究起搏图形与导管位置的关系。 结果 电极导管到位率 97.5 % ,心脏有效起搏率97.5 % ,体表心电图对床边电极导管插入时具有较高的定位价值 ,适用于多数患者。

Objective To evaluate the guiding value of electrocardiogram to bedside urgent cardiac pacing by invading mapping electrode catheter. Methods In 40 cases,all electrode catheters were inserted through right femora vein without x ray,and all hearts were urgently paced bedside,the operation guided by electrocardiogram.In lst to 15th day after operation,16 cases of them,the location of the catheters under fluoroscopy,the relationship between the morphology of electrocardiogram and the tip position were studied. Results The rate of electrode catheter arriving was 97.5%.The rate of effective pacing heart was 97.5%.The electrocardiogram conduced to our decision of catheter localization.The supervising of electrocardiogram during the procedure was suitable for majority. Conclusion The electrocardiogram is valuable in the guiding of the procedure of accurate and rapid bedside pacing.
