625 out of 4437 patients with an acute myocardial infarction (AMI) have been also diagnosed with atrioventricular (AV) block of II–III degrees, which makes 14,1 % of cases. In the course of study 97 patients have been implanted a pacemaker 12 to 23 days (15,8 ± 2,4 days on average) from acute infarction onset. Observations within 12 months show that stable AV block of II–III degrees has been detected in 49,5 % of cases, normal AV conduction – in 10,3 % and intermittently block – in 40,2 %. The article demonstrates that implantation of a pacemaker can be realized 2 weeks after AMI onset in the presence of AV block of II–III degrees combined with bundle branch block.
