(Tables 9, 10).
- the rats were anesthetized with ether, fixed on the back, and normal electrocardiograms were recorded (before modeling). Under sterile conditions, the left chest is lifted, the muscles are bluntly separated in the fourth intercostal space, the right chest is gently squeezed out of the heart, between the pulmonary artery cone and the left atrial appendage, and the coronary artery is ligated 2 to 3 mm from the origin of the left coronary artery. The left anterior descending artery is then immediately returned to the chest and the wound is sutured. Topical application of penicillin to prevent infection. Immediately after the operation, the electrocardiogram after ischemia (Omin after modeling) was recorded, and the height of the ST-T segment was measured.
