A technique that makes use of real-time-directed M-mode echocardiography is described in which the fetal heart is evaluated for suspected cardiac arrhythmias. Simultaneous M-mode recording of aortic, mitral, or tricuspid valvular leaflet excursion and/or atrioventricular wall motion defines timing relationships between atrial and ventricular systole. With the use of the techniques described in this report, normal as well as abnormal atrioventricular contractions can be quantitated and cardiac arrhythmias accurately defined.
本文描述了一种利用实时定向M型超声心动图的技术，该技术用于评估疑似心律失常的胎儿心脏。同时记录主动脉、二尖瓣或三尖瓣瓣叶活动和/或房室壁运动的M型超声心动图，可确定心房和心室收缩之间的时间关系。使用本报告中所述的技术，可以对正常和异常的房室收缩进行量化，并准确界定心律失常。
