lography were evaluated for their ability to estimate myocardial ischemia. In 14 closed-chest, sedated dogs, a small and larger region of ischemia were produced by inflating balloon occluders on the left anterior descend-ing coronary artery. The systemic arterial pressure, atrial-paced heart rate, global ejection fraction by radio-nuclide and contrast ventriculography, regional wall-motion abnormalities (as the percentage of abnormally contracting segments), and regional myocardial blood flow (using the microsphere technique) were measured during an initial control period, two separate ischemic periods, and a final control period. The regional ische-mic weights based on myocardial blood flow ranged from 0 to 38.5 g and were grouped as zero,...
