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.
