经静脉埋藏式三腔起搏器治疗恶性心律失常及心衰的疗效观察

Clinical Observation on the Treatment of Malignant Arrhythmia and Heart Failure by Three Chamber Pacemaker Implantation

目的探讨经静脉埋藏式三腔起搏器治疗恶性心律失常及心衰疗效。方法抽取我院20例恶性心律失常及心衰患者,通过经静脉埋藏式三腔起搏器进行治疗。对比本组患者治疗前后心脏各指标变化情况,并统计不良反应发生情况。结果治疗前本组患者心功能Ⅱ级6例、Ⅲ级14例,术后Ⅰ级10例、Ⅱ级10例,且左心室舒张末径(57.47±6.56)mm与左心室射血分数(39.39±5.28)%均较治疗前(64.58±6.69)mm、(29.41±5.30)%明显改善,差异有统计学意义(P<0.05);不良反应发生率为5.0%(1/20)。结论经静脉埋藏式三腔起搏器治疗恶性心律失常及心衰患者效果显著,可有效改善患者心功能,且不良反应发生率较低。

Objective To investigate the efficacy of three chamber pacemaker implantation in patients with malignant arrhythmia and heart failure.Methods20 cases of malignant arrhythmia the changes of cardiac indexes were compared before and after treatment. And the incidence of adverse reactions was compared. Results Before treatment, the cardiac function of 6 cases was gradeⅡ, 14 cases of gradeⅢ, after treatment, 10 cases of grade I, 10 cases of gradeⅡ. And left ventricular end diastolic diameter （57.47±6.56） mm and left ventricular ejection fraction （39.39±5.28）% were better than before treatment （64.58±6.69） mm, （29.41±5.30）%, and the difference was statistically significant （P〈0.05）; The incidence of adverse reactions was 5% （1/20）.ConclusionThe effect of three chamber pacemaker implantation for malignant arrhythmias and heart failure is significant, which can effectively improve the cardiac function of patients, and the incidence of adverse reactions is low.
