The majority if not all of the reentrant circuit involved in this type of tachycardia is formed by the Purkinje fibres of the left bundle branch, particularly the left posterior fascicle. In general, slowly conducting Purkinje fibres (P1) form the antegrade limb, and normally conducting Purkinje fibres (P2) form the retrograde limb of the reentrant circuit of the ventricular tachycardia originating from the left posterior fascicle. Elimination of the critical Purkinje elements in the reentrant circuit is the route to successful ablation. While the reentrant circuit identified by activation mapping provides the roadmap to ablation targets, comparing the difference in the His-ventricular interval during sinus rhythm and tachycardia also helps to identify the critical site in the reentrant circuit.<\/p>","DOI":"10.15420\/aer.2019.07","type":"journal-article","created":{"date-parts":[[2020,2,25]],"date-time":"2020-02-25T04:31:28Z","timestamp":1582605088000},"page":"249-254","source":"Crossref","is-referenced-by-count":3,"title":["Idiopathic Left Ventricular Tachycardia Originating in the Left Posterior Fascicle"],"prefix":"10.15420","volume":"8","author":[{"given":"Hongwu","family":"Chen","sequence":"first","affiliation":[{"name":"Division of Cardiology, First Affiliated Hospital of Nanjing Medical University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kit","family":"Chan","sequence":"additional","affiliation":[{"name":"Division of Cardiology, University of Hong Kong Shenzhen Hospital, Shenzhen, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sunny S","family":"Po","sequence":"additional","affiliation":[{"name":"Section of Cardiovascular Diseases and Heart Rhythm Institute, University of Oklahoma Health Sciences Center, Oklahoma City, OK, US"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minglong","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Cardiology, First Affiliated Hospital of Nanjing Medical University, Nanjing, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6096","published-online":{"date-parts":[[2020,2,11]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Nakagawa M, Takahashi N, Nobe S, et al.
