Figures

Figure 1
Figure 1. Fractionated Electrograms may indicate Wavelet Collision or Far Field Signals, as validated from monophasic action potentials
This far-field signal or noise may cause overestimation of the spectral DF (bottom left), that is avoided using time domain autocorrelation (reproduced from reference (24) with permission).
Figure 2
Figure 2. Alternans of Action Potentials Preceding AF
The patient showed typical AFL with APD alternans at the cavotricupid isthmus (but not high right atrium, HRA), that became exaggerated in amplitude preceding conduction block (asterisked), period multupling and AF (reproduced from reference (12) with permission from the American Heart Association).
