Seven patients bad no cardiovascular disease, 5 patients had hypertension. 3 patients had coronary heart disease, and 1 patient bad congenital heart disease. Eight patients had paroxysmal atrial fibrillation for a mean duration of 80 \u00b1 61 months, and eight patients had persistent atrial fibrillation for a mean duration of 68 \u00b1 119 months. Except for one patient who received digoxin throughout the study, alt patients received the same Class I or III antiarrhythmic agent throughout the study. The implantable atrial defibrillator successfully converted 50 (93%) of 54 spontaneous episodes of atrial fibrillation in 12 patients. During the initial 3 months of clinical follow\u2010up, the atrial defibrillator documented 261 \u00b1 270 hours of atrial fibrillation compared with 126 \u00b1 172 hours (P = 0.01) during the subsequent 3 months. The left atrial size decreased from 4.4 \u00b1 0.7 cm at the time of atrial defibrillator implantation to 4.1 \u00b1 0.6 cm (P = 0.02) 6 months later. The number of atrial fibrillation recurrences did not change. These findings were observed in the absence of changes in drug therapy. No complications were observed.<\/jats:p><jats:p> <jats:italic>Conclusion<\/jats:italic>: Restoration and maintenance of sinus rhythm in patients with atrial fibrillation by repeated cardioversion with an implantable atrial defibrillator was associated with a reduction in the total arrhythmia duration and a reduction in left atrial size. These results suggest that maintenance of sinus rhythm with the atrial defibrillator may reverse the remodeling process associated with atrial fibrillation.<\/jats:p>","DOI":"10.1111\/j.1540-8167.1999.tb00296.x","type":"journal-article","created":{"date-parts":[[2007,4,20]],"date-time":"2007-04-20T13:53:17Z","timestamp":1177077197000},"page":"1200-1209","source":"Crossref","is-referenced-by-count":36,"title":["Effect of the Implantable Atrial Defibrillator on the Natural History of Atrial Fibrillation"],"prefix":"10.1111","volume":"10","author":[{"given":"HUNG\u2010FAT","family":"TSE","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CHU\u2010PAK","family":"LAU","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"CHEUK\u2010MAN","family":"YU","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"KATHY L.F.","family":"LEE","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GREGORY F.","family":"MICHAUD","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BRADLEY P.","family":"KNIGHT","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"FRED","family":"MORADY","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S.
