Noninvasive long-term ECG monitoring vs. loop recorder implantation for the atrial fibrillation management.

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.
