A repeat electrophysiology study and catheter ablation were applied. Baseline AH and HV intervals were 100 and 55\u00a0ms during normal sinus rhythm (NSR), respectively. Programmed atrial stimulation induced a short RP narrow complex tachycardia (HV interval 22\u00a0ms) with an incomplete right bundle branch block configuration and right axis deviation. Tachycardia was terminated with ATP 5\u00a0mg injection. An atrial premature beat within the His refractory period advanced and reset tachycardia. Entrainment performed from the coronary sinus and left ventricle both showed a post\u2010pacing interval minus tachycardia cycle length (TCL) of 90\u00a0ms. After confirming the diagnosis, left atrial mapping along mitral annulus was performed using trans\u2010septal access and accessory pathway potentials were recorded during NSR and tachycardia at the superior mitral annulus. An irrigated ablation catheter guided by 3\u2010D mapping was used to perform ablation during tachycardia. Tachycardia terminated immediately during the first RF application with ensuing automaticity exhibiting a warm\u2010up during radiofrequency delivery and a cooling down upon the suspension of ablation. Therefore, all phenomena of Mahaim\u2010fiber associated tachycardia were observed. In this case, we describe an antidromic atrio\u2010ventricular reentry tachycardia using a left atrio\u2010fascicular fiber inserting into the proximal left anterior fascicle.<\/jats:p>","DOI":"10.1111\/pace.15052","type":"journal-article","created":{"date-parts":[[2024,11,16]],"date-time":"2024-11-16T18:38:10Z","timestamp":1731782290000},"page":"63-67","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["A narrow complex tachycardia with a short HV interval: What is the mechanism?"],"prefix":"10.1111","volume":"48","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9844-486X","authenticated-orcid":false,"given":"Hongwu","family":"Chen","sequence":"first","affiliation":[{"name":"Division of Cardiology the First Affiliated Hospital of Nanjing Medical University  Nanjing China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hao","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Cardiology Zhejiang Greentown Cardiovascular Hospital  Hangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Jin","sequence":"additional","affiliation":[{"name":"Division of Cardiology Zhejiang Greentown Cardiovascular Hospital  Hangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0097-0026","authenticated-orcid":false,"given":"Ashkan","family":"Ehdaie","sequence":"additional","affiliation":[{"name":"Heart Institute Cedars Sinai Medical Center  Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xunzhang","family":"Wang","sequence":"additional","affiliation":[{"name":"Heart Institute Cedars Sinai Medical Center  Los Angeles California USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-8174-0945","authenticated-orcid":false,"given":"Lang","family":"He","sequence":"additional","affiliation":[{"name":"Division of Cardiology Zhejiang Greentown Cardiovascular Hospital  Hangzhou China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7835-1335","authenticated-orcid":false,"given":"Minglong","family":"Chen","sequence":"additional","affiliation":[{"name":"Division of Cardiology the First Affiliated Hospital of Nanjing Medical University  Nanjing China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2024,11,16]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/jce.14852"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCEP.119.007853"}],"container-title":["Pacing and Clinical Electrophysiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/pace.15052","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T02:57:30Z","timestamp":1741748250000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/pace.15052"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,11,16]]},"references-count":2,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2025,1]]}},"alternative-id":["10.1111\/pace.15052"],"URL":"https:\/\/doi.org\/10.1111\/pace.15052","archive":["Portico"],"relation":{},"ISSN":["0147-8389","1540-8159"],"issn-type":[{"value":"0147-8389","type":"print"},{"value":"1540-8159","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,11,16]]},"assertion":[{"value":"2024-05-18","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-07-18","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2024-11-16","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
