2.6 Observing the perioperative myocardial injury and the other complications
At LAO 45°, we observed whether the patient developed acute cardiac tamponade and followed changes in their condition within 24h after LBBAP surgery. Simultaneously, before and after pacemaker implantation, the patients underwent electrocardiography and serum troponin and myocardial enzyme spectrum detection to observe whether the implanted pacing electrode damaged the blood vessels of heart, resulting in myocardial ischemia and myocardial infarction.
