Anatomical Determinants of the Left Atrial Electrograms: Wall Thickness and Myocardial Fat Infiltration

INTRODUCTION: Electrogram peak-to-peak voltage depends on atrial wall structure and mapping configuration. We evaluated the relationship between computed tomography-derived atrial wall thickness, intramyocardial fat, myocardial muscle thickness, and electrogram voltage obtained w...
