目的观察50例不同模式起搏器植入的疗效及并发症。方法对50例不同模式的永久性起搏器植入患者进行随访观察,对术中疗效及术后各种并发症进行分析。结果不同模式的心脏永久性起搏治疗均能显著改善患者症状。(总有效率为98%)。生理性起搏(DDD及AAI模式)的治疗效果优于非生理性起搏(VⅥ模式),分别增加左室射血分数50·2%,7·3%(P<0·01);手术并发症二者差异无统计学意义,但非手术并发症VⅥ(20%)明显多于DDD及AAI模式(3%)。结论心脏永久性起搏能有效改善心律失常患者的功能,DDD及AAI模式优于VⅥ模式。
Objective To observe the curative effect and complications of 50 different modes of pacemaker implantation. Methods Fifty patients with different modes of permanent pacemaker implantation were observed and followed up. The curative effect and various postoperative complications were analyzed. Results Different modes of cardiac permanent pacing therapy significantly improved patient symptoms. (Total efficiency of 98%). Physiological pacing (DDD and AAI mode) was superior to non-physiologic pacing (VVI mode) and increased left ventricular ejection fraction by 50.2% and 7.3% respectively (P <0.01) There was no significant difference between the two groups in the complication, but the VVI (20%) in nonoperative complications was significantly more than that in DDD and AAI models (3%). Conclusions Permanent cardiac pacing can effectively improve the function of arrhythmia patients. DDD and AAI are better than VVI.
