Differences in continuous spectra of fractionated electrograms in paroxysmal versus persistent atrial fibrillation

INTRODUCTION Quantitative measurements are helpful to discern fractionated electrograms in paroxysmal and persistent atrial fibrillation (AF), and may be useful to detect optimal ablation sites. However, electrical activation events can be transient, leading to erroneous estimates of electrogram properties. Measurement of continuous changes in electrogram… CONTINUE READING
