QUANTITATIVE P WAVE CHARACTERISTICS DURING SINUS RHYTHM ARE ALTERED BY CAVO-TRICUSPID ISTHMUS ABLATION

Typical atrial flutter is a common arrhythmia that is effectively treated with ablation at the cavotricuspid-isthmus (CTI) to achieve bidirectional conduction block. Currently, bidirectional block can only be assessed by intracardiac pacing maneuvers. We hypothesized that quantitative
