Tâm thất trái tâm trương quan hệ áp lực khối lượng thu được trong một bệnh nhân đại diện tại phần còn lại (), sau khi ngừng nhịp trong một tập phim của nhịp gây ra đau thắt ngực (), và vào cuối của một tắc bóng vành (). Áp lực tâm thất trái tâm trương-khối lượng mối quan hệ trong nhịp do thiếu máu cục bộ | 248 . Bronzwaer and . Paulus Pressure mmHg Figure . Diastolic left ventricular pressure-volume relations obtained in a representative patient at rest upon cessation of pacing during an episode of pacing-induced angina O and at the end of a balloon coronary occlusion . The diastolic left ventricular pressure-volume relation during pacing-induced ischemia was shifted upward and the end-diastolic left ventricular pressure-volume relation at the end of a balloon coronary occlusion was shifted rightward compared with the diastolic left ventricular pressure-volume relation at rest. Volume ml sion 127 32 mm Hg . Left ventricular stroke work index was significantly different from rest R 75 17 g m at the end of balloon coronary occlusion 43 14 g m p vs. R and PI but not during pacing-inducing ischemia PI 77 15 g m Figure . Heart rate showed a similar increase from beats min at rest to beats min during pacing-induced ischemia p and to beats min at the end of balloon coronary occlusion p . Regional wall motion data of ischemic and nonischemic segments showed a significant drop in percent systolic shortening of the ischemic segment from 40 11 at rest R to 25 9 during pacing induced ischemia PI p vs. R and to 6 9 at the end of balloon coronary occlusion p vs. R and PI . The nonischemic segment showed no change in percent systolic shortening during pacing-induced ischemia PI and a decrease in percent systolic shortening from Figure . Bar graphs showing left ventricular stroke work index LVSWI left ventricular end-diastolic pressure LVEDP and left ventricular end-diastolic volume index LVEDVI observed at rest during pacing-induced ischemia PI and at the end of balloon coronary occlusion CO . 17. Coronary Artery Disease 249 50 8 at rest R to 43 8 at the end of balloon coronary occlusion p vs. R and PI . The change in percent systolic shortening of the nonischemic segment was explained by motion of the
