Figure.
Figure.. Atrial tachycardia by standard activation mapping (left) and algorithmically reinterpreted maps (middle) focused on a site of complex electrograms (right).
Electrograms at this site (right atrium near the coronary sinus) are difficult to interpret in isolation. The novel algorithm found that marking these electrograms to produce highly curved vectors of propagation i.e. localized reentry best resolved the global vector patterns. Ablation here terminated AT. Standard mapping less accurately portrayed this map as a focal mechanism. Reproduced with permission from figure 4 of Anter et al .
