Sinus rhythm ECG showed normal conduction intervals with a His\u2013ventricular interval of 41\u00b14 ms. All patients had monomorphic VT (cycle length: 337\u00b188 ms) with a relatively narrow QRS (123\u00b112 ms), and they did not respond to verapamil during the initial presentation. VT exhibited right bundle-branch block\/superior axis configuration in 11 patients (73%) and inferior axis in 3 (20%). In 1 patient (7%), VT exhibited left bundle-branch block\/superior axis configuration. During ablation, spontaneous VT occurred in 3 patients (20%) and nonentraintable VT or identical premature ventricular complex was induced in 9 (60%). A high-frequency presystolic Purkinje potential was recorded during VT\/premature ventricular complex, preceding the QRS by 25\u00b116 ms. VT recurrence was observed in 4 patients (27%), and among them, 3 underwent pacemap-guided ablation during the first session. A second ablation with activation mapping guidance eliminated the VT during the 88\u00b18-month follow-up.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Among idiopathic VT cases referred for ablation, 2.8% were focal non-reentrant fascicular tachycardia, which had distinct clinical characteristics and usually originated from the left posterior fascicle, and less commonly from the left anterior fascicle and right ventricular Purkinje network. Catheter ablation is effective, whereas pacemap-guided approach is less efficacious.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1161\/circep.116.004177","type":"journal-article","created":{"date-parts":[[2016,10,12]],"date-time":"2016-10-12T01:51:39Z","timestamp":1476237099000},"update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":44,"title":["Non-Reentrant Fascicular Tachycardia"],"prefix":"10.1161","volume":"9","author":[{"given":"Ahmed Karim","family":"Talib","sequence":"first","affiliation":[{"name":"From the Cardiovascular Division, Faculty of Medicine, Tsukuba University, Japan (A.K.T., A.N., K.K., M.I., Y.S., K.A.);
