Abstract
Objective To evaluate the echo-guided cardiac resynchronization therapy (CRT) for chronic heart failure (CHF) patients. Methods Thirty five CHF patients received CRT, the AV and VV intervals were optimized by echocardiography at 1 week, 3 and 9 months after pacemaker implantation. The echocardiography,heart function classification, distance of 6 min walk test, QRS interval of al patients were evaluated during fol ow-up. Results The levels of NYHA functional class, 6-min walk dis-tance of 35 patients were improved during fol ow-up;the left ventricular ejection fraction (LVEF), left ventricular end-diastolic di-mension (LVEDd), the standard deviation of regional time intervals in 12 left ventricular (Ts-12SD) and interventricular mechanical delay (IVMD) on echocardiography were significantly improved (P<0.01) after device implantation. The improvement of these parameters was more markedly in later than earlier time after implantation (P<0.01). Conclusion CRT can improve the biventric-ular mechanical synchrony and cardiac function with AV/VV delay optimization guided by echocardiography.关键词
