Entrainment mapping was consistent with a macroreentrant circuit rotating in a clockwise fashion under the pulmonic valve. After termination of the VT in a critical isthmus located on the conal free wall, a pace map proximal to the site of successful ablation was consistent with a change in QRS morphology. This change in QRS morphology suggested critical isthmus block and successful ablation, which was confirmed by noninducibility with programmed stimulation.<\/jats:p><jats:p> <jats:italic>Conclusion:<\/jats:italic> Evidence of conduction block can be used as an additional endpoint for successful ablation of VT. <jats:italic>(J Cardiovasc Electrophysiol, Vol. 21, pp. 320\u2013324, March 2010)<\/jats:italic><\/jats:p>","DOI":"10.1111\/j.1540-8167.2009.01596.x","type":"journal-article","created":{"date-parts":[[2009,9,2]],"date-time":"2009-09-02T18:06:45Z","timestamp":1251914805000},"page":"320-324","source":"Crossref","is-referenced-by-count":9,"title":["New Endpoint for Ablation of Ventricular Tachycardia: Change in QRS Morphology with Pacing at Protected Isthmus as Index of Isthmus Block"],"prefix":"10.1111","volume":"21","author":[{"given":"RUPA","family":"BALA","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SANDHYA","family":"DHRUVAKUMAR","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"SHUAIB A.","family":"LATIF","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"FRANCIS E.","family":"MARCHLINSKI","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,2,22]]},"reference":[{"key":"e_1_2_5_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.1998.tb00217.x"},{"key":"e_1_2_5_3_2","doi-asserted-by":"crossref","first-page":"801","DOI":"10.1111\/j.1540-8159.2004.00531.x","article-title":"Radiofrequency catheter ablation of a macroreentrant ventricular tachycardia late after surgical repair of Tetralogy of Fallot using the electroanatomic mapping (CARTO)","volume":"27","author":"Rostock T","year":"2004","journal-title":"Pacing Clin Electrophysiol"},{"key":"e_1_2_5_4_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.1998.tb00217.x"},{"key":"e_1_2_5_5_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.2004.00531.x"},{"key":"e_1_2_5_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.1993.tb02340.x"},{"key":"e_1_2_5_7_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1997.tb00808.x"},{"key":"e_1_2_5_8_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8159.1993.tb02340.x"},{"key":"e_1_2_5_9_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.1997.tb00808.x"},{"key":"e_1_2_5_10_2","doi-asserted-by":"publisher","DOI":"10.1017\/S1047951105001010"},{"key":"e_1_2_5_11_2","doi-asserted-by":"crossref","first-page":"301","DOI":"10.1016\/j.hrthm.2004.05.009","article-title":"Radiofrequency catheter ablation of ventricular tachycardia in children and young adults with congenital heart disease","volume":"3","author":"Morwood JG","year":"2004","journal-title":"Heart Rhythm"}],"container-title":["Journal of Cardiovascular Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1540-8167.2009.01596.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1540-8167.2009.01596.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,11,2]],"date-time":"2023-11-02T10:34:46Z","timestamp":1698921286000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1540-8167.2009.01596.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,2,22]]},"references-count":10,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2010,3]]}},"alternative-id":["10.1111\/j.1540-8167.2009.01596.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1540-8167.2009.01596.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":[[2010,2,22]]}}}
