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.
