title: M-mode omnidirectional recordings obtained from two-dimensional echocardiography.
abstract: A simple and inexpensive procedure to obtain M-mode tracings at any level or direction from two-dimensional echocardiograms is described. The method permits a complete M-mode visualization of 1) segmental motion of the cardiac walls, 2) structures difficult to reach with conventional procedures, and 3) two or more cardiac valves simultaneously.
