  Figure 1. Representative electroanatomic maps with anteroposterior view (A) and posteroanterior view (B) showing dispersion sites identified by VX1 system, Volta Medical (blue tags). Representative pictures of 2 distinct functional reentrant patterns identified in the patient (C, D). Left panels correspond to electrocardiographic imaging composite maps of the patient. Right panels correspond to noninvasive activation map (CardioInsight; Medtronic) of the atria showing spontaneous atrial fibrillation drivers. Black arrows depict the sequence of activation.
