Pulsed Doppler echocardiography was performed in 30 patients to assess the influence of mitral orifice area and velocity on the determination of mitral stroke volume and inflow. Aortic forward stroke volume and outflow were measured at the centre of the aortic annulus, and compared with mitral flow measurements calculated by three methods. Both mitral stroke volume and inflow derived from an instantaneous velocity-area method showed an excellent correlation with aortic flow measurements. The other two methods, which determined mitral stroke volume and inflow based on a mean mitral valve area and diastolic velocity integral, significantly underestimated mitral flow measurements. This study indicates that the instantaneous velocity-area method offers a reliable means for quantitating left ventricular inflow.
对30例患者进行了脉冲多普勒超声心动图检查，以评估二尖瓣口面积和速度对二尖瓣搏出量及流入量测定的影响。在主动脉瓣环中心测量主动脉前向搏出量和流出量，并与通过三种方法计算得到的二尖瓣血流测量值进行比较。通过瞬时速度-面积法得出的二尖瓣搏出量和流入量均与主动脉血流测量值具有良好的相关性。另外两种基于平均二尖瓣面积和舒张期速度积分来确定二尖瓣搏出量和流入量的方法，显著低估了二尖瓣血流测量值。本研究表明，瞬时速度-面积法为定量左心室流入量提供了一种可靠的方法。
