Abstract
The objectives of this study were: (1) to evaluate quantitatively the spatial resolution of pacemapping: and (2) to assess the predictive value and role of pacemapping for the catheter ablation of overt APs. Sixty‐three unipolar leads were used instead of the standard 12‐lead ECG to acquire more information and assess the intrinsic accuracy of pacemapping. Spatial resolution was evaluated in 19 patients for whom data were recorded during bipolar ventricular pacing near the AV ring using the three electrode pairs of a quadripolar ablation catheter with a 5mm interelectrode spacing. The predictive value was assessed in 27 patients with overt APs who underwent HF ablation: their data were recorded during pacing at the site of successful ablation and at one or two sites where HF energy delivery was ineffective. Data from different beats were compared visually by using body surface potential maps and quantitatively by computing average correlation coefficients (r). Heproducibility was high for paced beats (r = 0.98 ± 0.02). Displacements of 5 mm of the pacing site could be detected with a sensitivity of 90% and a specificity of 87%. Correlation between pacing at successful ablation sites and preexcited sinus rhythm was low (r = 0.79 ± 0.11) and the ablation outcome could be predicted with a negative prediction accuracy of 87% and a positive prediction accuracy of 49%. Despite an excellent spatial resolution, pacemapping is of limited value for the identification of successful AP ablation sites, probably because APs can be interrupted at some distance from their ventricular insertion point.

Sixty‐three unipolar leads were used instead of the standard 12‐lead ECG to acquire more information and assess the intrinsic accuracy of pacemapping. Spatial resolution was evaluated in 19 patients for whom data were recorded during bipolar ventricular pacing near the AV ring using the three electrode pairs of a quadripolar ablation catheter with a 5mm interelectrode spacing. The predictive value was assessed in 27 patients with overt APs who underwent HF ablation: their data were recorded during pacing at the site of successful ablation and at one or two sites where HF energy delivery was ineffective. Data from different beats were compared visually by using body surface potential maps and quantitatively by computing average correlation coefficients (r). Heproducibility was high for paced beats (r = 0.98 ± 0.02). Displacements of 5 mm of the pacing site could be detected with a sensitivity of 90% and a specificity of 87%. Correlation between pacing at successful ablation sites and preexcited sinus rhythm was low (r = 0.79 ± 0.11) and the ablation outcome could be predicted with a negative prediction accuracy of 87% and a positive prediction accuracy of 49%. Despite an excellent spatial resolution, pacemapping is of limited value for the identification of successful AP ablation sites, probably because APs can be interrupted at some distance from their ventricular insertion point.</abstract><subject lang="en"><genre>Keywords</genre><topic>electrocardiograpby</topic><topic>body surface potential mapping</topic><topic>radiofrequency ablation</topic><topic>Wolff‐Parkinson‐White syndrome</topic></subject><relatedItem type="host"><titleInfo><title>Pacing and Clinical Electrophysiology</title></titleInfo><genre type="Journal">journal</genre><identifier type="ISSN">0147-8389</identifier><identifier type="eISSN">1540-8159</identifier><identifier type="DOI">10.1111/(ISSN)1540-8159</identifier><identifier type="PublisherID">PACE</identifier><part><date>1997</date><detail type="volume"><caption>vol.</caption><number>20</number></detail><detail type="issue"><caption>no.</caption><number>3</number></detail><extent unit="pages"><start>683</start><end>694</end><total>12</total></extent></part></relatedItem><identifier type="istex">1B0C0DD7E148D91AC797C7210EF39783D5726304</identifier><identifier type="DOI">10.1111/j.1540-8159.1997.tb03887.x</identifier><identifier type="ArticleID">PACE683</identifier><recordInfo><recordContentSource>WILEY</recordContentSource><recordOrigin>Blackwell Publishing Ltd</recordOrigin></recordInfo></mods></metadata><serie></serie></istex></record>Pour manipuler ce document sous Unix (Dilib)
