Determinants of left atrial local impedance: Relationships with contact force, atrial fibrosis, and rhythm

ConclusionsCF and rhythm significantly affect the measured LIr of LA myocardium. Optimal catheter-tissue coupling may be better achieved with higher levels of CF and in AF rather than SR. Atrial fibrosis, as assessed by LIr  but not bipolar voltage, affected the CF–LI relationship.
