The electrogram was analyzed for several features, including pattern ("QS" or "initial R"). Unipolar pattern: Overall, a "QS" pattern was seen at 55% of unsuccessful, 75% of temporarily successful, and 90% of permanently successful sites. For the atrial group, the respective frequencies were 53%, 77%, and 92%, and for the ventricular group, 57%, 73%, and 86%. The difference in pattern distribution between unsuccessful and permanently successful sites was significant for all groups: overall, P < 0.0001; atrial group, P = 0.0005; ventricular group, P = 0.02. Absence of a "QS" pattern (i.e., "initial R") predicted a 92% chance of unsuccessful ablation. Additional features: Activation times were significantly shorter at permanently successful than at unsuccessful (P < 0.0001) or temporarily successful sites (P = 0.0002). No significant differences were found in atrial or ventricular amplitudes or in A/V ratios. Intrinsic deflection slew was lower at temporarily successful sites (P = 0.03 vs all other sites).</AbstractText><AbstractText Label="CONCLUSION" NlmCategory="CONCLUSIONS">Ablation at sites revealing an "initial R" pattern (i.e., absent "QS") is very unlikely to be successful. Activation time is shorter at successful sites. These features are equally applicable when mapping the atrial potential as when mapping the ventricular potential.</AbstractText></Abstract><AuthorList CompleteYN="Y"><Author ValidYN="Y"><LastName>Barlow</LastName><ForeName>M A</ForeName><Initials>MA</Initials><AffiliationInfo><Affiliation>Division of Cardiology, The University of Western Ontario, London, Canada.</Affiliation></AffiliationInfo></Author><Author ValidYN="Y"><LastName>Klein</LastName><ForeName>G J</ForeName><Initials>GJ</Initials></Author><Author ValidYN="Y"><LastName>Simpson</LastName><ForeName>C S</ForeName><Initials>CS</Initials></Author><Author ValidYN="Y"><LastName>Murgatroyd</LastName><ForeName>F D</ForeName><Initials>FD</Initials></Author><Author ValidYN="Y"><LastName>Yee</LastName><ForeName>R</ForeName><Initials>R</Initials></Author><Author ValidYN="Y"><LastName>Krahn</LastName><ForeName>A D</ForeName><Initials>AD</Initials></Author><Author ValidYN="Y"><LastName>Skanes</LastName><ForeName>A C</ForeName><Initials>AC</Initials></Author></AuthorList><Language>eng</Language><PublicationTypeList><PublicationType UI="D016428">Journal Article</PublicationType><PublicationType UI="D013485">Research Support, Non-U.S. Gov't</PublicationType></PublicationTypeList></Article><MedlineJournalInfo><Country>United States</Country><MedlineTA>J Cardiovasc Electrophysiol</MedlineTA><NlmUniqueID>9010756</NlmUniqueID><ISSNLinking>1045-3873</ISSNLinking></MedlineJournalInfo><CitationSubset>IM</CitationSubset><MeshHeadingList><MeshHeading><DescriptorName UI="D000293" MajorTopicYN="N">Adolescent</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D000328" MajorTopicYN="N">Adult</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D000368" MajorTopicYN="N">Aged</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D016275" MajorTopicYN="N">Atrial Function</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D017115" MajorTopicYN="Y">Catheter Ablation</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D002648" MajorTopicYN="N">Child</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D004562" MajorTopicYN="N">Electrocardiography</DescriptorName><QualifierName UI="Q000379" MajorTopicYN="Y">methods</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D005260" MajorTopicYN="N">Female</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D006801" MajorTopicYN="N">Humans</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D008297" MajorTopicYN="N">Male</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D008875" MajorTopicYN="N">Middle Aged</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D011237" MajorTopicYN="N">Predictive Value of Tests</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D013617" MajorTopicYN="N">Tachycardia, Supraventricular</DescriptorName><QualifierName UI="Q000503" MajorTopicYN="Y">physiopathology</QualifierName><QualifierName UI="Q000601" MajorTopicYN="Y">surgery</QualifierName></MeshHeading><MeshHeading><DescriptorName UI="D016896" MajorTopicYN="N">Treatment Outcome</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D016276" MajorTopicYN="N">Ventricular Function</DescriptorName></MeshHeading><MeshHeading><DescriptorName UI="D014927" MajorTopicYN="N">Wolff-Parkinson-White Syndrome</DescriptorName><QualifierName UI="Q000503" MajorTopicYN="Y">physiopathology</QualifierName><QualifierName UI="Q000601" MajorTopicYN="Y">surgery</QualifierName></MeshHeading></MeshHeadingList></MedlineCitation><PubmedData><History><PubMedPubDate PubStatus="pubmed"><Year>2000</Year><Month>3</Month><Day>10</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="medline"><Year>2000</Year><Month>3</Month><Day>25</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate><PubMedPubDate PubStatus="entrez"><Year>2000</Year><Month>3</Month><Day>10</Day><Hour>9</Hour><Minute>0</Minute></PubMedPubDate></History><PublicationStatus>ppublish</PublicationStatus><ArticleIdList><ArticleId IdType="pubmed">10709708</ArticleId></ArticleIdList></PubmedData></pubmed><affiliations><list><country><li>Canada</li></country><region><li>Angleterre</li><li>Grand Londres</li></region><settlement><li>Londres</li></settlement></list><tree><noCountry><name sortKey="Klein, G J" sort="Klein, G J" uniqKey="Klein G" first="G J" last="Klein">G J Klein</name><name sortKey="Krahn, A D" sort="Krahn, A D" uniqKey="Krahn A" first="A D" last="Krahn">A D Krahn</name><name sortKey="Murgatroyd, F D" sort="Murgatroyd, F D" uniqKey="Murgatroyd F" first="F D" last="Murgatroyd">F D Murgatroyd</name><name sortKey="Simpson, C S" sort="Simpson, C S" uniqKey="Simpson C" first="C S" last="Simpson">C S Simpson</name><name sortKey="Skanes, A C" sort="Skanes, A C" uniqKey="Skanes A" first="A C" last="Skanes">A C Skanes</name><name sortKey="Yee, R" sort="Yee, R" uniqKey="Yee R" first="R" last="Yee">R.
