摘　　要：目的评价实时三维超声心动图对心力衰竭(心衰)患者左室收缩不同步参数与M-型、组织多普勒超声等技术的准确性和可行性比较。方法对36例心衰患者和33例健康志愿者同时采用M-型超声(ME)、组织多普勒(TDI)和RT-3DE等技术测量左室收缩非同步性参数。结果(1)心衰组所有不同步参数均明显高于正常组,P均<0.01;(2)RT-3DE、TDI和ME诊断心衰组患者心室内收缩不同步的阳性率分别为83%、75%和64%;(3)3种方法诊断心室内收缩不同步的Kappa值比较,结果为RT-3DE与TDI之间Kappa值=0.750,吻合度较高。RT-3DE与ME之间Kappa值=0.437,吻合度一般。结论(1)RT-3DE能在同一个心动周期内比较左室各节段的不同步性;(2)RT-3DE和TDI在评价心衰患者左室内收缩不同步的吻合度较高,且RT-3DE有可能优于TDI。Objective To explore the feasibility and accuracy of real-time 3-dimensional echocardiography(RT-3DE),ME M mode and TDI for quantitative evaluation of left ventricular systolic asynchrony in patients with heart failure.Methods Thirty-six heart failure(HF) patients and 36 healthy volunteers underwent M-mode echocardiography(ME),tissue Doppler imaging(TDI) and RT-3DE.The indices of systolic asynchrony was obtained on ME、TDI and RT-3DE.Results All the indices of systolic asynchrony were significantly larger in...
