ATRIAL FIBRILLATION RISK IN OUT-PATIENTS WITH CARDIAC PACEMAKERS, IMPLANTED DUE TO ATRIOVENTRICULAR BLOCK
Abstract
To indentify the predictors of atrial fibrillation (AF) in patients with implanted artificial pacemakers (IPM), 65 such patients were followed up for 6 months. The AF group included 18 (27,7%) patients, while the comparison group consisted of 47 AF-free individuals. AF risk markers included increased maximal length and dispersion of P wave at electrocardiography, as well as increased P wave dispersion (by 13,9%) during the follow-up. In addition, volume, but not linear, characteristics of left atrium (LA) were 1,44-1,77 times greater in AF patients than in AF-free participants. During the follow-up period, linear LA parameters increased regardless of AF (by 19.8% and 14,8%, respectively), while AF volume significantly increased in AF individuals exclusively, which pointed to structural LA remodelling, and not only LA dilatation.
