Does noninvasive estimation using the inverse problem of electrocardiography accurately reconstruct dominant frequency maps compared to intracardiac electrograms in patients with atrial fibrillation?
p-value: p=<0.01
Noninvasive reconstruction of atrial frequency maps using the inverse problem of electrocardiography provides accurate estimation of dominant frequency, outperforming temporal distribution pattern reconstruction.
Pedrón-Torrecilla et al. (2016) conducted an observational in Atrial fibrillation (n=4). Noninvasive estimation of dominant frequency by solving the inverse problem of electrocardiography vs. Intracardiac electrograms was evaluated on Relative errors in voltage, phase, and frequency spectrum compared to intracardiac electrograms (p=<0.01). Noninvasive estimation of atrial dominant frequency maps via the inverse problem of electrocardiography achieved an 8.8 ± 4.4% relative error, providing higher accuracy than temporal patterns.
