Fetal arrhythmias can be challenging to diagnose, even with the use of 2-dimensional, M-mode, and spectral Doppler sonography of myocardial or blood flow signals to determine the rate, synchrony, and timing. Color Doppler sonography combined with M-mode echocardiography uses the myocardium and blood flow to provide a robust evaluation of cardiac rhythm. Limited descriptions of color M-mode sonography have been published. This article describes the systematic application of the color M-mode technique using 4 specific clinical case examples and contrasts this technique with more conventional approaches to fetal arrhythmia diagnosis.
胎儿心律失常的诊断具有挑战性,即使使用二维、M 模式和频谱多普勒超声技术来检测心肌或血流信号的速率、同步性和时相。彩色多普勒超声结合 M 模式超声心动图使用心肌和血流来提供对心律的有力评估。彩色 M 模式超声的有限描述已经发表。本文通过 4 个具体的临床病例示例描述了彩色 M 模式技术的系统应用,并将该技术与更传统的胎儿心律失常诊断方法进行了对比。
