The aim of this study was to compare the impact of various recording techniques on the electrogram voltage after the delivery of ablation therapy in the human right atrium (RA).<\/jats:p><jats:p> <jats:italic>Material and Methods:<\/jats:italic> Noncontact mapping was performed in 27 patients with typical atrial flutter (mean age = 63 \u00b1 16, males = 20). Noncontact unipolar and bipolar electrograms were obtained before and after cavotricuspid isthmus (CTI) linear ablation. All unipolar electrograms were acquired with both wide\u2010band filtering (0.5\u2013300 Hz) and narrow\u2010band filtering (32\u2013300 Hz). The unipolar voltage measurements included both the peak\u2010to\u2010peak voltage and peak\u2010negative voltage (PNV) for both filter settings.<\/jats:p><jats:p> <jats:italic>Results:<\/jats:italic> A comparison of the electrogram voltage along the ablation line before and after the ablation demonstrated a greater reduction in the unipolar PNV with wide\u2010band filtering (70 \u00b1 24%) than in any of the other recording modalities (P = 0.03). It was the most sensitive and specific recording technique to predict conduction block (cut\u2010off Value 0.35 mV; sensitivity = 94.4% and specificity = 80%). A comparison of the electrogram voltage between the ablated atrial myocardium and nearby nonablated myocardium showed that the unipolar PNV with the wide\u2010band filtering remained the most sensitive method to detect the acute ablative tissue injury, whereas the peak\u2010to\u2010peak bipolar voltage was the most specific method.<\/jats:p><jats:p> <jats:italic>Conclusion:<\/jats:italic> The noncontact unipolar electrogram using the PNV with wide\u2010band filter settings (0.5\u2013300 Hz) provided the most sensitive recording technique for detecting acute ablative tissue injury.<\/jats:p>","DOI":"10.1111\/j.1540-8167.2007.00803.x","type":"journal-article","created":{"date-parts":[[2007,4,4]],"date-time":"2007-04-04T17:53:46Z","timestamp":1175709226000},"page":"617-622","source":"Crossref","is-referenced-by-count":11,"title":["Optimal
