However, a case with complete AV block was reported to histologically show fibrotic changes solely in the atrial muscles but neither in the AV node nor in the His bundle, indicating a possible relation between AV block and atrial tachyarrhythmias. To test a hypothesis that AV block and Af are causally interrelated, we investigated the incidence and electrophysiological characteristics of Af in complete AV block.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Methods and Results<\/jats:italic>\n            Forty-two patients with persistent complete AV block underwent the electrophysiological study. Patients with spontaneous\/electrically induced Af were compared with the other patients with respect to their electrophysiological variables. Of the 42 patients, Af was transiently induced by electrical stimulation in 5 patients (11.9%), while persistent Af was observed in 2 patients (4.8%, AH and HV block). AV block in the 5 patients with induced Af was invariably due to AH block. AH block complicated by persistent\/induced Af was marked by relatively short RR intervals, significantly short junctional recovery time, and impaired intra-atrial conduction.\n          <\/jats:p>\n          <jats:p>\n            <jats:italic>Conclusions<\/jats:italic>\n            Electrically induced Af in complete AV block was associated frequently with complete AH block. These patients were characterized differently from the commonly recognized AV block and therefore may stand as a unique subgroup of AH block.\n          <\/jats:p>","DOI":"10.1161\/01.cir.95.3.650","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:41:02Z","timestamp":1339461662000},"page":"650-654","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Incidence of Induced Atrial Fibrillation\/Flutter in Complete Atrioventricular Block"],"prefix":"10.1161","volume":"95","author":[{"given":"Takeshi","family":"Yamashita","sequence":"first","affiliation":[{"name":"the Second Department of Internal Medicine, Faculty of Medicine, University of Tokyo (Japan)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuji","family":"Murakawa","sequence":"additional","affiliation":[{"name":"the Second Department of Internal Medicine, Faculty of Medicine, University of Tokyo (Japan)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kohsuke","family":"Ajiki","sequence":"additional","affiliation":[{"name":"the Second Department of Internal Medicine, Faculty of Medicine, University of Tokyo (Japan)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masao","family":"Omata","sequence":"additional","affiliation":[{"name":"the Second Department of Internal Medicine, Faculty of Medicine, University of Tokyo (Japan)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_1_1_2","unstructured":"Watanabe Y Dreifus LS.
