Validation of the Frequency Spectra Obtained from the Noncontact Unipolar Electrograms During Atrial Fibrillation

Introduction: Noncontact mapping (NCM) can record virtual unipolar electrograms (Egs) from multiple sites simultaneously; therefore, it has the potential to perform simultaneous frequency mapping during atrial fibrillation (AF). The aim of this study was to validate the frequency spectra of the noncontact unipolar Egs in both atria.
