Repolarization information simplifies interpretation of atrial electrophysiology. Simultaneous monophasic action potentials (top) and bipolar electrograms (bottom) in human left atrium during atrial fibrillation (AF). Top: Beat-to-beat tracking of repolarization time, indicated by time to ≈70% repolarization (APD70) in the monophasic action potential, shows that clinical electrograms in human AF may poorly indicate true local activation. Several deflections (nonfractionated and fractionated) fall well within APD70 and likely are far-field (see text and Narayan et al).
