Figure 1 . Mechanistic subtypes of LIA and their frequency in LA of 25 patients with persistent AF (Shi et al J Arrhythmia 2020)7 .
Figure 2 Preferential conduction zone on anterior wall of a patient with persistent AF. During a 520ms temporal window, LIA was detected on the mid-anterior wall with a combination of slow conduction and collision, followed by a LRA in the spatial region. From Shi et al. J Arrhythmia 2020.
