Myocardial infarction is a potential complication of pacemaker implantation using active fixation right ventricle (RV) lead owing to direct mechanical damage to the coronary artery. Introduction: Right ventricle (RV) septal pacing has emerged as a more favorable pacing site compared to apical RV pacing. Concern over proximity of anterior septal sites to the coronary arteries has been raised. We report a case of myocardial infarction owing to actively fixating the RV lead into the left anterior descending (LAD) coronary artery. Acute myocardial infarction should be considered when evaluating chest pain following pacemaker implantation.
