Key result
Electrographic flow mapping accurately localizes 100% of simulated AF focal sources during ipsilateral pacing.
Why the study?
Existing mapping algorithms have been unable to localize triggers that serve as drivers of AF, while electrographic flow mapping offers a method to visualize near real-time cardiac wavefront propagation.
Does electrographic flow (EGF) mapping accurately detect simulated sources of atrial fibrillation in an animal model?
Does electrographic flow (EGF) mapping accurately detect simulated sources of atrial fibrillation in an animal model?
Electrographic flow mapping accurately visualizes flow patterns and pinpoints simulated focal sources of atrial fibrillation in an animal model, suggesting its potential utility for targeting focal ablations.

EGF mapping merits human validation for AF source localization; hypothesis-generating in animals and should not yet change practice.
Kong et al. (2023) studied Atrial fibrillation (n=9). Electrographic flow (EGF) mapping vs. Subthreshold pacing or contralateral pacing was evaluated on Accurate localization of simulated focal source during pacing at or above capture threshold in the ipsilateral atrium. Electrographic flow mapping accurately localized simulated focal sources of atrial fibrillation in 100% of cases during pacing at or above threshold in the ipsilateral atrium.
