The m-mode was the preferred imaging modality in the early days of ultrasound. m-mode is defined as time motion display of the ultrasound wave along a chosen ultrasound line. it provides a monodimensional view of the heart. all of the reflectors along this line are displayed along the time axis. the advantage of the m-mode is its very high.

M-mode echocardiography an mmode echocardiogram is not a "picture" of the heart, but rather a diagram that shows how the positions of its structures change during the course of the cardiac cycle. m-mode recordings permit measurement of cardiac dimensions and motion patterns. also facilitate analysis of time relationships with other.
