Evaluation of RETRO-Mapping for Electrophysiological Features including Direction of Plane Activity during Atrial Fibrillation using Multipolar Catheters in Humans.

RETRO-Mapping can measure electrophysiological features of activation activity and this proof-of-concept study suggests that this can be extended to the detection of plane activity in three types of AF. Wavefront direction may have a role in future work for predicting plane activity. For this study, we focused more on the ability of the algorithm to detect plane activity and less the differences between the types of AF. Future work should be in validating these results with a larger dataset and comparing with other types of activation such as rotational, collision, and focal. Ultimately, this work can be implemented in real-time for prediction of wavefronts during ablation procedures. This article is protected by copyright. All rights reserved.
