We hypothesized that a dual\u2010loop reentry could be surmised from \u201cparadoxical delayed capture\u201d of the proximal part of the circuit having a longer interval from the stimulus to the captured beat compared with the distal part of the circuit. In 6 of 12 patients with CCW AFL, during entrainment from the septal side of the posterior blocking line, the interval from the stimulus to the last captured beat was longer at the RA free wall than at the isthmus position. In these six patients with paradoxical delayed capture, flutter cycle length (FCL) was 227 \u00b1 12 ms and postpacing interval minus FCL was significantly shorter at the posterior blocking line than at the RA free wall (20 \u00b1 11 ms vs 48 \u00b1 33 ms, P &lt; 0.05). In two of these patients, early breakthrough occurred at the lateral TA. A posterior block line was confirmed in all six patients in the sinus venosa area by intracardiac echocardiography.<\/jats:p><jats:p> <jats:italic>Conclusion:<\/jats:italic> Half of the patients with common type AFL had a dual\u2010loop macroreentrant circuit consisting of an anterior loop (circuit around the TA) and a posterior loop (circuit around the inferior vena cava and the posterior blocking line). <jats:italic>(J Cardiovasc Electrophysiol, Vol. 15, pp. 679\u2010685, June 2004)<\/jats:italic><\/jats:p>","DOI":"10.1046\/j.1540-8167.2004.03579.x","type":"journal-article","created":{"date-parts":[[2004,5,28]],"date-time":"2004-05-28T07:24:19Z","timestamp":1085729059000},"page":"679-685","source":"Crossref","is-referenced-by-count":17,"title":["Entrainment Mapping of Dual\u2010Loop Macroreentry in Common Atrial Flutter:"],"prefix":"10.1111","volume":"15","author":[{"given":"AKIRA","family":"FUJIKI","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KUNIHIRO","family":"NISHIDA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MASAO","family":"SAKABE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MASATAKA","family":"SUGAO","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"TAKAYUKI","family":"TSUNEDA","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KOICHI","family":"MIZUMAKI","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HIROSHI","family":"INOUE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,5,28]]},"reference":[{"key":"e_1_2_6_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.56.5.737"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(93)91014-9"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.92.7.1839"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.94.3.398"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(97)89299-5"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.99.13.1700"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.101.13.1568"},{"key":"e_1_2_6_9_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.103.25.3092"},{"key":"e_1_2_6_10_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.96.11.3904"},{"key":"e_1_2_6_11_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.93.3.502"},{"key":"e_1_2_6_12_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.101.6.631"},{"key":"e_1_2_6_13_2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.99.21.2771"},{"key":"e_1_2_6_14_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(99)00211-9"},{"key":"e_1_2_6_15_2","doi-asserted-by":"publisher","DOI":"10.1253\/circj.66.1113"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1046%2Fj.1540-8167.2004.03579.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1046\/j.1540-8167.2004.03579.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T04:54:57Z","timestamp":1694408097000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1046\/j.1540-8167.2004.03579.x"}},"subtitle":["New Insights into the Atrial Flutter Circuit"],"short-title":[],"issued":{"date-parts":[[2004,5,28]]},"references-count":14,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2004,6]]}},"alternative-id":["10.1046\/j.1540-8167.2004.03579.x"],"URL":"https:\/\/doi.org\/10.1046\/j.1540-8167.2004.03579.x","archive":["Portico"],"relation":{},"ISSN":["1045-3873","1540-8167"],"issn-type":[{"value":"1045-3873","type":"print"},{"value":"1540-8167","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,5,28]]}}}
