Abstract :
The feasibility of atrial activation time imaging is investigated based on data sets of four patients who underwent an electrophysiologic study. Several pacing protocols with pacing sites at the right atrial appendage, coronary sinus, and high right atrium were part of the study and were employed to reconstruct the associated atrial activation time patterns. The localization error was estimated to be between 8 and 14 mm.
