Quantitative assessment of temporal and spatial ventricular wall motion in normal and infarcted human left ventricles.

abstract：:Reperfusion therapy has lowered the mortality in patients suffering acute myocardial infarction. Failure to reperfuse is associated with significantly higher risk of short- and long-term mortality. Detection of reperfusion is thus important. In a prospective pilot study, we used continuous on-line computerized vectorc...
