Development of a method of evaluating cardiac performance using interactive computer graphics.

The authors discuss an objective method of analyzing local wall motion to detect and measure the pattern of contraction of the left ventricle using computer graphics. The method's advantages include: (a) the use of modular hardward and software, which can be extended and upgraded; (b) a minimal expenditure of time and money; (c) uniformly calculated results; and (d) a graphic and legible report.
