The signals from patients with old myocardial infarction (MI,N = 7) and arrhythmogenic right ventricular dysplasia (ARVD, N = 1) were amplified and passed through a bandpass (100-300 Hz) filter. The departure maps, LP isopotential maps, and LP\n                    <jats:sub>30<\/jats:sub>\n                    area maps were generated and superimposed. The LP\n                    <jats:sub>30<\/jats:sub>\n                    duration was determined as the section between the filtered QRS endpoints and points thirty milliseconds (ms) before. Isopotential maps of the LPs showed distinct positive and negative regions. In 7 cases with MI, the extreme was related to the zones indicated by the departure maps, and the LP\n                    <jats:sub>30<\/jats:sub>\n                    area maps also corresponded to the departure areas. In 1 case of ARVD, endocardial fragmented activity directly recorded at the right ventricle closely corresponded with the region on the LP\n                    <jats:sub>30<\/jats:sub>\n                    area map.\n                  <\/jats:p>\n                  <jats:p>\n                    In conclusion, body surface LP isopotential maps and LP\n                    <jats:sub>30<\/jats:sub>\n                    area maps may provide useful information concerning the spatial distribution of endocardial fragmentation.\n                  <\/jats:p>","DOI":"10.1177\/000331979004100808","type":"journal-article","created":{"date-parts":[[2007,11,26]],"date-time":"2007-11-26T17:46:29Z","timestamp":1196099189000},"page":"639-646","source":"Crossref","is-referenced-by-count":1,"title":["Detection of the Spatial Distribution of Late Potentials by Body Surface Mapping Using Forty-Five Unipolar, Leads"],"prefix":"10.1177","volume":"41","author":[{"given":"Kenji","family":"Nakai","sequence":"first","affiliation":[{"name":"Department of Clinical Pathology, Iwate Medical University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minoru","family":"Syobuzawa","sequence":"additional","affiliation":[{"name":"Department of Clinical Pathology, Iwate Medical University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chuichi","family":"Itoh","sequence":"additional","affiliation":[{"name":"Department of Clinical Pathology, Iwate Medical University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomohisa","family":"Miyakawa","sequence":"additional","affiliation":[{"name":"2nd Department of Internal Medicine, Iwate Medical University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masataka","family":"Kato","sequence":"additional","affiliation":[{"name":"2nd Department of Internal Medicine, Iwate Medical University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tetsu","family":"Onishi","sequence":"additional","affiliation":[{"name":"Heart Institute of Japan, Tokyo Women's Medical School"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroshi","family":"Kasanuki","sequence":"additional","affiliation":[{"name":"Heart Institute of Japan, Tokyo Women's Medical School"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saichi","family":"Hosoda","sequence":"additional","affiliation":[{"name":"Heart Institute of Japan, Tokyo Women's Medical School"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1990,8,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9149(78)90820-2"},{"key":"atypb2","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.63.5.1172"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.64.2.235"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.67.5.1129"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(83)80020-4"},{"key":"atypb6","first-page":"79","volume":"36","author":"Nakai K.","year":"1988","journal-title":"Kokyu to Junkan"},{"key":"atypb7","first-page":"207","volume":"18","author":"Nakai K.","year":"1988","journal-title":"Jpn Coll Cardiol"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.72.1.105"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.54.6.906"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.43.3.406"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.74.6.1323"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9149(83)80020-4"},{"key":"atypb13","unstructured":"Gardner PI, Ursell PC, Pham TD, et al: Experimental chronic ventricular tachycardia: Anatomic and electrophysiologic substrates.
