Inverse-computed voltage, phase, and dominant frequency (DF) maps for simulated AF with a left-to-right DF gradient. A: Voltage, phase, and DF maps for generated epicardial electrograms (EGM). B: Voltage, phase, and DF maps for inverse computed electrograms (icEGM) without added noise. C: Voltage, phase, and DF maps for icEGM with added noise on surface potentials at 10 dB SNR.
