Description
  • Komplexně frakcionované síňové elektrogramy (KFAE) reprezentují elektrofyziologický substrate fibrilace síní (FiS). Vývoj algoritmů zpracování signal pro identifikaci komplexně frakcionovaných síňových elektrogramu je zásadní pro rozvoj ablačních strategií FiS. Provedli jsme porovnání dvou metod kvantifikace síňových elektrogramů (A-EGM) s různým stupněm frakcionace. První metoda M1 stanovila průměrný interval mezi diskrétními vrcholy A-EGM algoritmem dříve implementovaným v comerčně dostupném elektroanatomickém mapovacím system. Druhá metoda M2 zahrnovala robustní předzpracování signal a popis síňových signal distribucí peak-to-peak sensitivity. Využili jsme sadu 113 A-EGM signalů 1.5s délky, které byli slepě hodnoceny 3 nezávislými experty do čtyř kategorií frakcionace. (cs)
  • Complex fractionated atrial electrograms (CFAEs) represent the electrophysiologic substrate for atrial fibrillation (AF). Progress in signal processing algorithms to identify CFAEs sites is crucial for the development of AF ablation strategies. We compared two methods to discriminate atrial electrograms (A-EGMs) with different degree of fractionation. First method (M-1) assessed the average interval between discrete A-EGM spikes detected based on peak-to-peak voltage sensitivity, signal width, and refractory interval criteria (algorithm previously implemented in commercially available electroanatomic mapping system). Second method (M-2) assessed the number of fractionated segments defined by amplitude, duration, and minimum inter-segment distance. Parameters of M-1 method were optimized by exhaustive search (peak-to-peak sensitivity of 0.02 mV, signal width of 8 ms, and refractory interval of 14 ms) with respect to particular experimental dataset.
