Computer assisted M-mode echocardiogram analysis.

An analysis system has been developed to aid the quantitative interpretation of echocardiograms. A small and relatively inexpensive desk-top computer, which requires no modification is used. The analysis system enables a variety of complex continuous measurements to be made. The include left ventricular dimension changes, velocities and "work" diagrams. Using the digitiser in the system, a series of options in the operating program allow the analysis steps to be tailored to specific clinical or research requirements. Analysed waveforms can be output singly or superimposed to allow physiological and measurement variabilities to be studied. The system is now being used in several hospitals, and all report favourably on its flexibility and ease of use.
