With the exclusion of nine patients who were lost to follow-up, 61 were fitted with pacemakers. The overall survival of patients with established and potential dysfunction was similar and apparently indistinguishable from that of the normal population. Pacemaker implantation had little discernible effect on mortality though it reduced some incapacitating symptoms. These findings suggest that sinoatrial dysfunction is a relatively benign condition. Hence pacing should probably not be adopted as a routing measure but be reserved for patients with troublesome symptoms.<\/jats:p>","DOI":"10.1136\/bmj.280.6208.139","type":"journal-article","created":{"date-parts":[[2009,4,2]],"date-time":"2009-04-02T18:32:30Z","timestamp":1238697150000},"page":"139-141","source":"Crossref","is-referenced-by-count":165,"title":["Survival in sinoatrial disorder (sick-sinus syndrome)."],"prefix":"10.1136","volume":"280","author":[{"given":"D B","family":"Shaw","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R R","family":"Holman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J I","family":"Gowers","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[1980,1,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"28","DOI":"10.1001\/archinte.1978.03630250012007","article-title":"Sick sinus syndrome","volume":"138","author":"IKaplan, B.M.","year":"1978","unstructured":"IKaplan BM.
