In the first case interventricular septum movements in a man of 65 and in one of 24, with type B W.P.W., were recorded echocardiographically. The septum described a typical expulsive "beak" movement followed by a paradoxical anterior movement during ventricular systolic ejection. In the second case, the septum gives rise in the pre-expulsive phase to a marked posterior incisure before going through its normal posterior movement in the systolic phase. Stress is laid on the aspecificity of the series of septal movements in the first case as it is common to other conditions, namely total left branch block, extrasystole originating from the night ventricle and many cases of temporary intracardial electrostimulation with floating catheter in the right ventricle. It is considered however that echocardiographic investigation in type B W.P.W. is useful in any case because, unlike surface ECG which is always the same, it offers information about the extent of the pre-excited zone.
在第一例中,对一名65岁男性以及一名24岁患B型预激综合征(W.P.W.)的患者进行了超声心动图检查,记录了室间隔运动情况。室间隔呈现典型的喷射性“喙状”运动,随后在心室收缩期射血过程中出现矛盾的向前运动。在第二例中,室间隔在喷射前期出现明显的向后切迹,然后在收缩期经历正常的向后运动。重点强调了第一例中室间隔运动系列的非特异性,因为它在其他情况中也很常见,即完全性左束支传导阻滞、源自右心室的期前收缩以及许多使用右心室漂浮导管进行临时心内电刺激的病例。然而,人们认为,无论如何,对B型预激综合征进行超声心动图检查都是有用的,因为与始终相同的体表心电图不同,它能提供有关预激区范围的信息。
