球囊漂浮电极导管床旁心脏临时起搏术40例临床分析

目的观察漂浮电极导管床旁临时心脏起搏的临床应用效果。方法对40例严重缓慢型心律失常患者在床旁体表心电图监护指导下，通过Seldinger穿刺技术，在无X线透视条件下将临时起搏漂浮电极导管送入右心室．通过体表心电图QRS波群确定电极位置。记录放置电极导管所花费的时间与平均起搏时间，观察临时起搏操作并发症。结果40例患者穿刺均获成功，安置球囊漂浮电极导管平均操作时间（9．1±2．1）min，起搏时间1-15d，中位时间5．5d，电极脱位2例，无其他并发症。结论床旁漂浮电极导管可在没有X线设备下紧急起搏而不需搬动危重患者，具有操作简单、起搏迅速、疗效肯定及相对安全的特点，适合在基层医院推广应用。

Clinical analysis of floating catheter in bedside temporary cardiac pacing in 40 patients

Objectives To observe the clinical effect of floating catheter in bedside temporary cardiac pacing.Methods Forty patients with severe bradyarrhythmia were included in this study and floating catheter for temporary cardiac pacing was propelled into right ventricle by Seldinger technique without fluoroscopy,under the guidance of bedside electrocardiography monitoring.The location of electrods were confirmed by QRS wave.The duration of placing floating catheter and the average time of pacing were recorded,and the complications of pacing were observed.Results Forty patients were successfully punctured,with an average duration of placing floating catheter of(9.1±2.1) min,pacing time of 1-15 days(median time of 5.5 days).Two cases were on loosen electrode,but no other complications were found.Conclusions Bedside floating electrode catheter can be used without fluoroscopy and replacement of critical patients in emergent pacing,with characters of easy performing,rapid pacing,definite effects and relative safety,and it is suitable for promotion in primary hospitals.
