Changes in the ST-segment displacement in the surface 15-lead electrocardiogram induced by single and simultaneous occlusion of the left anterior descending and circumflex coronary arteries in anesthetized pigs. (A) shows the 15-lead ECG recorded in a representative case at baseline and after single and double 5-min occlusion of the left anterior descending and left circumflex coronary arteries. (B) illustrates the mean (bars) and the standard error of the mean (whiskers) of the ST-segment displacement recorded in the 15-lead ECG in the 4 pigs of left anterior and left circumflex coronary arteries group. From top to bottom the panels illustrate the ST-segment changes induced after left anterior, left circumflex, and double coronary occlusion. LCX, left circumflex coronary artery; LAD, left anterior descending coronary artery.
