二尖瓣波群又称二尖瓣波群。（2）二尖瓣波群（包括三区及二区）：主要观察二尖瓣及左右室的活动情况。当主动脉瓣返流时在二尖瓣波群上可见彩色血流线在主动脉瓣关闭之后，二尖瓣开放之前，由室间隔处向下直指二尖瓣曲线的DF段，有时这种彩色血流能在二尖瓣前侧持续显现于舒张全期，流线方向是由左上向右下。
多波群能输出多波群、阶梯波、点格、黑白、副载波及扫频（范围：100kHz~10MHz）等信号。输入多波群或扫频信号，信号幅度为1V（峰?峰值），测出?3dB点的视频宽带，应符合5.2.2.1条要求。实际上对于监视器清晰度的评判一方面可以通过图像主观评价判别出来，另一方面也可以通过专用仪器----带多波群图像的图像信号发生器的显示结果判别出来。
心室波群 2、P-R间期固定（可为正常或延长），突然出现一个P波不能下传，发生心室波群脱落。 2、P-R间期逐渐延长，直到P波不能下传，发生心室波群脱落，脱落后的P-R间期又为最短。
