1 High-density mapping of the tachycardia circuit in atrioventricular nodal reentrant tachycardia

2 Figure 1 Frozen activation map of atrioventricular node reentrant tachycardia (AVNRT), with yellow representing earlier activation “colliding” with late (purple) activation along the slow pathway region (using CS 5–6 as reference). The map shows the portion of activation illustrated (rainbow segment) out of the entire mapped cycle length (maroon circle). There is a slow-pathway potential noted on ablation catheter electrograms during sinus rhythm (right side, unipolar [U1:D6 and U1:D7] and bipolar [B:D6–7]).

3 Figure 2 Alternative, posterior electoanatomic view with electrograms during tachycardia. The electroanatomic map displays the band of activation (rainbow segment) out of the entire mapped cycle length (marroon circle). Counterclockwise activation is illustrated (also see supplemental video). The coronary sinus electrograms show slightly eccentric activation due to catheter position with near zero ventriculoatrial activation time.
