摘要: This invention relates to an ex vivo use of the instantaneous frequency modulation (iFM) signal of cardiac activations and to an ex vivo use of the instantaneous amplitude modulation (iAM) signal obtained from the sequence of amplitude excursions of said activations for detecting ‘driver’ or ‘high-hierarchy’ regions and/or the cardiac spots that display the footprint of rotational activations in the heart of a subject with cardiac fibrillation without requiring panoramic simultaneous acquisition.
