ATa merits testing as an ARI alternative in atrial mapping; animal data leave open clinical translation.
The area under the repolarization wave (ATa) is a more robust measure than activation recovery interval (ARI) for identifying spatial action potential duration heterogeneities in the atria.
Vigmond et al. (2009) studied this question.
