Chronic obstructive pulmonary disease is the fourth leading\n   cause of mortality worldwide. It is defined as a persistent airflow\n   limitation usually progressive and not fully reversible to treatment. The\n   diagnosis of chronic obstructive pulmonary disease and severity of disease is\n   confirmed by spirometry. Chronic obstructive pulmonary disease produces\n   electrical changes in the heart which shows characteristic electrocardiogram\n   pattern. The aim of this study was to observe and evaluate diagnostic values\n   of electrocardiogram changes in chronic obstructive pulmonary disease\n   patients with no other comorbidity. Material and Methods. We analyzed 110\n   electrocardiogram findings in clinically stable chronic obstructive pulmonary\n   disease patients and evaluated the forced expiratory volume in the first\n   second, ratio of forces expiratory volume in the first second to the fixed\n   vital capacity, chest radiographs and electrocardiogram changes such as p\n   wave height, QRS axis and voltage, right bundle branch block, left bundle\n   branch block, right ventricular hypertrophy, T wave inversion in leads V1-V3,\n   S1S2S3 syndrome, transition zone in praecordial lead and QT interval.\n   Results. We found electrocardiogram changes in 64% patients, while 36% had\n   normal electrocardiogram. The most frequent electrocardiogram changes\n   observed were transition zone (76.36%) low QRS (50%) and p pulmonale\n   (14.54%). Left axis deviation was observed in 27.27% patients. Conclusion.\n   Diagnostic values of electrocardiogram in patients with chronic obstructive\n   pulmonary disease suggest that chronic obstructive pulmonary disease patients\n   should be screened electrocardiographically in addition to other clinical\n   investigations.<\/jats:p>","DOI":"10.2298\/mpns1304126l","type":"journal-article","created":{"date-parts":[[2013,4,22]],"date-time":"2013-04-22T07:54:21Z","timestamp":1366617261000},"page":"126-129","source":"Crossref","is-referenced-by-count":9,"title":["Analysis of electrocardiogram in chronic obstructive pulmonary disease patients"],"prefix":"10.2298","volume":"66","author":[{"given":"Biljana","family":"Lazovic","sequence":"first","affiliation":[{"name":"Clinical Hospital Center Zemun, Department of Pulmonology and Cardiology, Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7123-140X","authenticated-orcid":false,"given":"Mirjana","family":"Zlatkovic-Svenda","sequence":"additional","affiliation":[{"name":"Clinical Rheumatology, Institute for Rheumatology, Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanja","family":"Mazic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Institute of Physiology, Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zoran","family":"Stajic","sequence":"additional","affiliation":[{"name":"Clinical Hospital Center Zemun, Department of Pulmonology and Cardiology, Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Djelic","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Institute of Physiology, Belgrade"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1078","container-title":["Medicinski pregled","Medical review"],"original-title":[],"language":"en","deposited":{"date-parts":[[2023,5,29]],"date-time":"2023-05-29T09:24:02Z","timestamp":1685352242000},"score":1,"resource":{"primary":{"URL":"https:\/\/doiserbia.nb.rs\/Article.aspx?ID=0025-81051304126L"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013]]},"references-count":0,"journal-issue":{"issue":"3-4","published-print":{"date-parts":[[2013]]}},"URL":"https:\/\/doi.org\/10.2298\/mpns1304126l","relation":{},"ISSN":["0025-8105","1820-7383"],"issn-type":[{"value":"0025-8105","type":"print"},{"value":"1820-7383","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013]]}}}
