双腔心脏起搏器对缓慢性心律失常患者的应用效果及对心功能的影响

Effect of Dual Chamber Pacemaker on Cardiac Function in Patients With Chronic Cardiac Arrhythmia

目的 探讨双腔心脏起搏器对缓慢性心律失常患者的应用效果及对心功能的影响。方法 选取我院2013年3月~2015年11月收治的67例缓慢性心律失常患者,随机分组,对照组33例,观察组34例,对照组行单腔心脏起搏器植入治疗,观察组行双腔心脏起搏器植入治疗,观察比较两组应用效果及心功能变化情况。结果 对照组的有效率为30.30%,观察组为73.53%,组间比较差异有统计学意义（P〈0.05）;观察组心率、心输出量、心脏指数均高于对照组,差异有统计学意义（P〈0.05）。结论 双腔心脏起搏器应用于缓慢性心律失常患者,可有效改善患者心功能,提高应用有效率。

Objective To investigate the effect of dual chamber pacemaker on cardiac function in patients with chronic cardiac arrhythmia. Methods 67 patients with chronic arrhythmia were treated in our hospital from March 2013 to November 2015, they were randomly divided into two groups, 33 cases in the control group and 34 cases in the observation group. Patients in the control group were treated with single chamber pacemaker implantation, and the observation group was treated with double chamber pacemaker implantation. We observed and compared the effects of the two groups and the changes of cardiac function. Results The effective rate of control group was 30.30%, the observation group was 73.53%, there was significant difference between the two groups（P0.05）, the heart rate, cardiac output and cardiac index in the observation group were higher than those in the control group, the difference was statistically significant（P0.05）. ConclusionDual chamber pacemaker used in patients with slow arrhythmia, can effectively improve the patient＇s cardiac function, improve the efficiency of the application.
