双腔心脏起搏器对缓慢性心律失常患者心功能的影响

目的探讨缓慢性心律失常患者实施双腔心脏起搏器治疗的临床效果。方法选取2017年3月至2018年9月在辽宁省人民医院治疗的100例缓慢性心律失常患者为研究对象,将患者分为2组,即对照组与观察组。对照组行单腔心脏起搏器,观察组行双腔心脏起搏器,两组患者均进行常规护理措施,对比分析两组患者治疗的疗效及治疗前后患者心功能和血液指标的改善情况。结果观察组治疗后的疗效显著高于对照组,差异有统计学意义(98.0%vs.84.0%,P<0.05)。治疗后,观察组患者心排血量[(4.22±0.45)L/min vs.(3.45±0.45)L/min,P<0.05]、左心室射血分数[59.89%±5.36%vs.54.11%±4.56%,P<0.05]、心脏指数[(2.55±0.26)L·min^-1·m^-2 vs.(2.12±0.22)L·min^-1·m^-2,P<0.05]明显高于对照组,差异有统计学意义。观察组患者左心室舒张末期内径[(4.11±0.18)cm vs.(4.77±0.26)cm,P<0.05]、左心房内径[(3.61±0.11)cm vs.(3.85±0.23)cm,P<0.05]、左心室收缩末期内径[(2.45±0.11)cm vs.(3.02±0.55)cm,P<0.05]明显低于对照组,差异有统计学意义。观察组患者全血黏度[(1.55±0.12)mPa/s vs.(1.89±0.22)mPa/s,P<0.05]、血小板聚集率(32.15%±4.45%vs.40.26%±5.22%,P<0.05)、血浆黏度[(6.45±0.45)mPa/s vs.(7.45±0.55)mPa/s,P<0.05]明显低于对照组,差异有统计学意义。结论对缓慢性心律失常患者实施双腔心脏起搏器治疗,效果明显,临床应用价值较高,值得推广。

Effect of double chamber pacemaker on cardiac function in patients with chronic arrhythmia

Objectives To study the clinical effect of double chamber pacemaker in patients with chronic arrhythmia.Methods Totally 100 patients with chronic arrhythmia treated in Liaoning Provincial People's Hospital from March 2017 to September 2018 were selected and divided into two groups,including control group and observation group.Patients in control group were given single-chamber pacemaker and patients in observation group were given double-chamber pacemaker.Patients in both groups were given routine nursing measures.Therapeutic effect,improvement of cardiac function and blood indicators pre and post-therapy of the two groups were compared and analyzed.Results Therapeutic effects of observation group was significantly higher than that of control group(98.0%vs.84.0%,P<0.05).After treatment,cardiac output[(4.22±0.45)L/min vs.(3.45±0.45)L/min,P<0.05],left ventricular ejection fraction(59.89%±5.36%vs.54.11%±4.56%,P<0.05),cardiac index[(2.55±0.26)L·min-1·m-2 vs.(2.12±0.22)L·min-1·m-2,P<0.05]of observation group were significantly higher than those of control group;Left ventricular end diastolic dimension[(4.11±0.18)cm vs.(4.77±0.26)cm,P<0.05],left atrial diameter[(3.61±0.11)cm vs.(3.85±0.23)cm,P<0.05],left ventricular endsystolic dimension[(2.45±0.11)cm vs.(3.02±0.55)cm,P<0.05]of observation group were significantly lower than those of control group;Blood viscosity[(1.55±0.12)mPa/s vs.(1.89±0.22)mPa/s,P<0.05],platelet aggregation rate(32.15%±4.45%vs.40.26%±5.22%,P<0.05),plasma viscosity[(6.45±0.45)mPa/s vs(.7.45±0.55)mPa/s,P<0.05]of observation group were significantly lower than those of control group.Conclusions Double chamber pacemaker is effective in treating patients with chronic arrhythmia.It is worthy of clinical promotion and application.
