The ECG changes that occurred during coronary stent placement in healthy swine were investigated in order to clarify the effect of surgical manipulation on the electrical activity of heart. The experiment was performed on nine female swine weighing 80+/-2.3 kg under halothane anaesthesia. Eighteen coronary stents were implanted into both left anterior and right coronary artery of the animals using a guiding catheter and transfemoral approach. Multi parameter patient monitor was used to examine closely the ECG changes during the procedure. ECG changes during coronary stent placement in healthy swine were closely related to the operative technique, but anesthetic agents may contribute to arrhythmias. 6F angiographic catheters did not cause coronary artery occlusion and myocardial ischemia in 80 kg pigs.
