目的对比分析右心室流出道起搏和右心室心尖部起搏对患者心功能和生活质量的影响。方法选取行右心室流出道起搏的患者11例作为治疗组;同期行右心室心尖部起搏的患者11例作为对照组。观察2组的手术情况、心功能分级、超声心动图改变及生活质量评分。结果2组在手术时间、QRS宽度改变上差异有统计学意义,在起搏感知阈值、电极阻抗、电极脱位率差异无统计学意义;随访12个月时,2组在心功能、超声心动图改变、生活质量评分方面,差异有统计学意义。结论与传统置入部位右心室心尖部起搏相比,右心室流出道起搏更接近正常生理性,可改善患者的心功能和生活质量。
Objective To compare the effects of right ventricular outflow tract pacing and right ventricular apical pacing on cardiac function and quality of life in patients. Methods Eleven patients with right ventricular outflow tract pacing were selected as the treatment group. Eleven patients with right ventricular apical pacing during the same period were selected as the control group. The operation conditions, heart function grading, echocardiographic changes and quality of life scores of the two groups were observed. Results There were significant differences in QRS width between the two groups in operation time, there was no significant difference in psoriasis threshold, electrode impedance and electrode dislocation rate between the two groups. At the 12-month follow-up, cardiac function and echocardiography were changed , Quality of life score, the difference was statistically significant. Conclusion Compared with the conventional right ventricular apical pacing, right ventricular outflow tract pacing is closer to normal physiology, which can improve the cardiac function and quality of life.
