Effects of Subthreshold Shocks on Wavelet Propagation during Atrial Fibrillation in Humans
OBJECTIVES: Our objectives are: first to investigate the effects of internal cardioversion energies on the wave fronts propagation in the right atrium immediately after the energy delivery; second, to track the time course of these effects. METHODS: The study is based on a measure of organization of the endoatrial electrograms obtained by a multipolar basket catheter inserted in the right atrium...
