The Electrophysiology of Atrial Fibrillation: From Basic Mechanisms to Catheter Ablation

Figure 10

Noninvasive body surface mapping. (a) The vest of 252 electrodes and the three-dimensional reconstruction of cardiac chambers with the computed tomography. The voltage at each point of the torso, taken from the 252 electrodes of the vest, is depicted with virtual electrograms on the surface of the atria. (b) Isochronous maps showing the rotational activity near the antrum of the right inferior PV.
