Effects of baseline P-wave duration and choice of atrial septal pacing site on shortening atrial activation time during pacing

EP Europace, 04/06/2012

Pacing at CSo is associated with the shortest P–wave duration (PWD). P–wave shortening is greatest in patients with baseline PWD of > 120 ms regardless of the pacing site. The results may have implications on the selection of candidates for ASP and the placement of the atrial septal lead, and warrant further evaluation in cases of permanent pacing in patients with paroxysmal atrial fibrillation (AF).
