We present in this paper experience of the use of implantable devices for long-term monitoring of cardiac rhythm after one stage operation of coronary artery bypass grafting (CABG) and radiofrequency ablation of atrial fibrillation (AF) source and results of a prospective randomized study, in which we included patients (n=95) with persistent AF and ischemic heart disease. These patients were randomized into 3 groups: with radiofrequency isolation of ostia of pulmonary veins (group 1, n=31), radiofrequency modified mini-maze procedure (group 2, n=30); CABG without AF elimination (control group 3, n=34). Implantable devices Reveal XT were used in 53 patients (21, 25, and 7 in groups 1, 2, and 3, respectively). According to data obtained with these devices AF was absent in 86.7, 95.6, 53%, and in 80, 86.2, 44.1% of patients in groups 1, 2, 3 after 1 and 2 years after operation, respectively). In 24% of patients Reveal devices also registered asymptomati-c arrhythmias. The use of implantable devices for monitoring of rhythm allowed to detect such arrhythmia and to provide timely correction of therapy.
