Directional Doppler-ultrasound has been found to be helpful in detecting disturbances of the left ventricular outflow tract, especially in aortic incompetence. Also in hypertrophic obstructive cardiomyopathy characteristic changes of flow in carotid artery have been demonstrated by directional Doppler-ultrasound, similar to those of the carotid pulse curve. These changes lead to diagnosis but usually do not allow an information about the hemodynamic status of hypertrophic obstructive cardiomyopathy. However, characteristic changes of the flow curve in the subclavian artery -- which are described in this paper -- seem to appear only in severe cases, when an intraventricular gradient was measurable, either at rest or under provocation test. So a combination of two non-invasive methods, echocardiography and directional Doppler-ultrasound of the carotid and the subclavian artery enables us to diagnose hypertrophic obstructive cardiomyopathy and at the same time informs us about hemodynamic conditions.
定向多普勒超声已被证明有助于检测左心室流出道的紊乱，尤其是在主动脉瓣关闭不全时。同样，在肥厚性梗阻性心肌病中，定向多普勒超声已显示出颈动脉血流的特征性变化，类似于颈动脉脉搏曲线的变化。这些变化有助于诊断，但通常无法提供有关肥厚性梗阻性心肌病血流动力学状态的信息。然而，本文所述的锁骨下动脉血流曲线的特征性变化似乎仅在严重病例中出现，即在静息或激发试验时可测量到心室内梯度的情况下。因此，将超声心动图与颈动脉和锁骨下动脉的定向多普勒超声这两种非侵入性方法相结合，使我们能够诊断肥厚性梗阻性心肌病，同时了解其血流动力学状况。
