Activation Timing and Atrial Fibrillation
Stopped early
Conditions studied: Arrhythmias, Cardiac, Atrial Fibrillation, Bundle Branch Block
In brief
This is a single center, non-randomized, unblinded study of patients who are followed at Essentia Health - St. Mary's Medical Center and who are referred for a clinically indicated diagnostic electrophysiology (EP) study with or without ablation. During the procedure, events of atrial fibrillation, sinus rhythm and bundle branch block that may occur during the course of the case will be saved electronically and analyzed offline. The stored data will be evaluated off-line for changes in activation timing of the near and far field ventricular signals of the stored events. This proof-of-concept study will attempt to assess whether atrial fibrillation, or bundle branch block can change activation timing compared to baseline sinus rhythm. If no significant activation change is seen, then this finding can be used as a basis to distinguish ventricular tachycardia from atrial fibrillation in future rhythm discrimination methods.
