Abstract Objective The objective of the study was to estimate the efficacy of a noninvasive ambulatory ECG monitoring (NIAM) in comparison with implantable loop recorder (ILR) in patients with atrial fibrillation (AF). Methods Thirty‐two patients 58 [47; 73] years of age with AF were included in the study. Patients were randomized into two groups: in group I ( n = 15), “Reveal XT” ILR was used for invasive ECG monitoring up to 3 months; in group II ( n = 17), “Spyder” device was used for NIAM up to 14 days. Results In both groups, at least one AF episode was detected during 14 days of monitoring. The overall count of AF episodes was 25 in NIAM group and 28 in ILR group. The mean time between AF start and its registration by a physician was 8 hr in NIAM group and 20 hr in ILR group ( p = .005). The diagnostic value parameters of NIAM were as follows: sensitivity—80.1%, specificity—73.1%; positive predictive value—74.1%; and negative predictive value—79.2%. The same parameters in ILR group were comparable with NIAM: sensitivity—78.6%; specificity—69%; positive predictive value—71%; and negative predictive value—77%. At the same time, continued monitoring with ILR for longer than two weeks did not lead to a significant change in the sensitivity and specificity of the method. Conclusion In patients with paroxysmal AF, the diagnostic value of both NIAM and ILR is comparable. An increase in the duration of ECG monitoring for longer than two weeks does not provide additional diagnostic information.
