一方面能够以非侵入方式获得左心室舒张功能信息,另一方面获得压力梯度信息,这使得多普勒超声成为临床实践中非常有吸引力的工具。然而,标准多普勒方法在区分正常和伪正常充盈模式方面的局限性,以及用于评估压力梯度的简化伯努利方程的局限性,都得到了很好的描述。在本手稿中,讨论了彩色 M 型多普勒超声心动图作为克服这些局限性的工具的作用。介绍了左心室充盈血流动力学的相关关键概念及其与彩色M型多普勒超声心动图的关系。
The ability to derive non-invasively information on left ventricular diastolic function on one hand and pressure gradients on the other hand, makes Doppler ultrasound a very attractive tool in clinical practice. However, the limitations of the standard Doppler approaches in differentiating between normal and pseudonormal filling patterns, together with the limitations of the simplified Bernoulli equation for assessing pressure gradients, are well described. In this manuscript the role of colour M-mode Doppler echocardiography as a tool that can overcome these limitations is discussed. Relevant key concepts of the haemodynamics of left ventricular filling and its relationship with colour M-mode Doppler echocardiography are introduced.
