摘　　要：目的探讨超声心动图在心脏再同步治疗(CRT)中的初步应用。方法随访我院2002年1月至2004年8月11例QRS波宽≥130 ms的心力衰竭患者行双心室起搏CRT前后6 min步行试验、心功能和主要超声心动图参数:左心室舒张末期内径、射血分数、二尖瓣反流程度和Q波至室壁峰值收缩速度时间延迟等的改变。结果有反应者8例,无反应者3例。有反应者临床症状和超声心动图主要参数改善显著。结论超声心动图在CRT病例选择、优化治疗和长期随访中具有重要作用。Objective To summarize the primary experience on usefulness of echocardiography in cardiac resynchronization therapy（CRT）. Methods Eleven patients, who had chronic heart failure with QRS duration more than 130 ms and underwent CRT in the hospital from Jan. 2002 to Aug. 2004, were followed up by echocardiography. Six min walk test, classification of heart failure, left ventricular ejection fraction, end-diastolic diameter, degree of mitral regurgitation and Q-wave-to peak systolic velocity delay were used to evaluate the efficacy of CRT. Results Eight respondors had significant improvement of clinical and echocardiographic data after CRT and other three were nonrespondors. Conclusions CRT is important for echocardiography in patient selection, therapeutic optimization and long term follow-up.
