右室流出道间隔部起搏QRS时限对原有心功能不全患者影响的比较
Comparison of the Effects of Right Ventricular Outflow Tract Septal Pacing QRS Time Duration on the Patients with Cardiac Insufficiency
摘要
Abstract
Objective:To observe the effects of paced QRS duration(pQRSd) on cardiac function in right ventricular outflow tract(RVOT) pacing patients who have slow arrhythmia requiring permanent pacemaker therapy associated with cardiac dysfunction.Method:52 patients associated with cardiac dysfunction,performed with right ventricular outflow tract paced,and the percentage of ventricular paced were greater than 90%,they were divided into A group(pQRSd<180 ms) and B group(pQRSd≥180 ms).NT-pro-BNP、LVEDD、LVESD、LVEF were analyzed and compared between two groups immediately after operation and 3 months after operation and observed the changes of cardiac function in patients.Result:NT-pro-BNP and cardiac ultrasound index of the two groups before operation were not statistically significant differences(P>0.05).After operation 3 months,the NT-pro-BNP,LVEDD,LVESD indexes of B group were significantly higher than those in A group,and the LVEF group of B was lower than A group,the differences were statistically significant (P<0.05).During pacemaker implantation, 3 months after surgery,two groups of patients with pacing threshold and lead impedance,R wave height,there were no significant differences (P>0.05).Conclusion:Patients with heart failure and need to be fitted with permanent cardiac pacemaker,RVOT interval paced QRS duration and postoperative cardiac function are closely related,pQRSd is wider,the heart function is poorer.关键词
