title: Semiautomated method for evaluation of left ventricular regional wall motion in coronary artery disease.
abstract: Regional left ventricular wall motion was independently assessed in 436 patients using both subjective visual inspection of ventriculograms and objective computer-determined percent change in the square root of the area between systolic and diastolic outlines. Agreement between subjective and objective techniques was greatest at the ventricular apex and least at the base and partly dependent on the number of abnormal segments present. Objective analysis of regional wall motion provides a permanent quantitative record of wall motion and shows good agreement with meticulous subjective inspection of ventriculograms. As such, it has potential as an adjunct to ventriculography.
