Objectives: This study sought to define the extent and spatial distribution of endocardial-epicardial dissociation (EED) in a swine model.
Background: The mechanisms underlying persistent atrial fibrillation (AF) remain unclear.
Methods: Sixteen swine underwent simultaneous endocardial and epicardial mapping using 32-electrode grid catheters.

Background: Endocardial-epicardial dissociation and focal breakthroughs in humans with atrial fibrillation (AF) have been recently demonstrated using activation mapping of short 10-second AF segments. In the current study, we used simultaneous endo-epi phase mapping to characterize endo-epi activation patterns on long segments of human persistent AF.
Methods: Simultaneous intraoperative mapping of endo- and epicardial lateral right atrium wall was performed in patients with persistent AF using 2 high-density grid catheters (16 electrodes, 3 mm spacing).

Background: The 3-dimensional (3D) nature of sinoatrial node (SAN) function has not been characterized in the intact human heart.
Objective: The purpose of this study was to characterize the 3D nature of SAN function in patients with structural heart disease (SHD) using simultaneous endocardial-epicardial (endo-epi) phase mapping.
Methods: Simultaneous intraoperative endo-epi SAN mapping was performed during sinus rhythm at baseline (SR) and postoverdrive suppression at 600 ms (SR) and 400 ms (SR) using 2 Abbott Advisor HD Grid Mapping Catheters.
