Figure presenting a propagation map, and patient selection. A, Example of a patient presenting atypical flutter tachycardia originating in the right atrium (RA). A modified inferior view of the RA representing the propagation history maps with critical isthmus on the medial posterolateral wall. The color red is used to indicate the leading edge of the wavefront with the trailing color bands showing earlier locations of the wavefront. CD1 represents the local charge density signal at the breakout point in the critical isthmus with a QS morphology. CS activation and lead I are also represented. B, A total number of 175 patients were referred for catheter ablation with scheduled Acutus mapping method. AcQMap was performed in 138 cases. Twenty patients with short episodes of atrial tachycardia were identified. AVNRT indicates atrioventricular nodal reentry tachycardia; AVRT, atrioventricular reentrant tachycardia; CD1, local unipolar charge signal; CS, coronary sinus; and SVT, supraventricular tachycardia.
