目的探讨三腔起搏器在心脏再同步化治疗(CRT)心力衰竭中的应用效果。方法选取赣南医学院第一附属医院2013年1月—2015年6月收治的心力衰竭患者40例,随机分为对照组20例与观察组20例。对照组患者给予常规治疗,观察组患者在对照组基础上应用三腔起搏器进行CRT。观察两组患者复发率、心脏功能(NYHA)分级、心电图QRS波宽度、左室舒张末期内径(LVDd)、左室射血分数(LVEF)。结果观察组复发率低于对照组,NYHA分级优于对照组,差异有统计学意义(P<0.05)。治疗前两组患者QRS、LVDd、LVEF比较,差异无统计学意义(P>0.05);治疗后观察组QRS宽度、LVDd小于对照组,LVEF高于对照组,差异有统计学意义(P<0.05)。结论三腔起搏器在CRT心力衰竭中的应用效果确切,可改善患者心功能指标,降低住院次数,从而提高患者生活质量。
Objective To investigate the application of three-chamber pacemaker in cardiac resynchronization therapy (CRT). Methods Forty patients with heart failure admitted to the First Affiliated Hospital of Gannan Medical College from January 2013 to June 2015 were randomly divided into control group (20 cases) and observation group (20 cases). Patients in the control group were given routine treatment. Patients in the observation group were treated with a triple-chamber pacemaker on the basis of the control group. The recurrence rate, NYHA classification, ECG QRS width, left ventricular end-diastolic diameter (LVDd) and left ventricular ejection fraction (LVEF) were observed. Results The recurrence rate of the observation group was lower than that of the control group, NYHA classification was better than the control group, the difference was statistically significant (P <0.05). There was no significant difference in QRS, LVDd and LVEF between the two groups before treatment (P> 0.05). After treatment, QRS width and LVDd in observation group were lower than those in control group, and LVEF was higher than that in control group (P <0.05) ). Conclusion The application of triple chamber pacemaker in CRT heart failure has definite effect, which can improve the cardiac function index, reduce the frequency of hospitalization and improve the quality of life of patients.
