The aim of this study was to analyze the relation between the occurrence and the severity of OSA and the parameters of ECG Holter monitoring in a group of patients with diagnosed OSA. Ninety-four patients with clinical suspicion of OSA were qualified for the study (mean age 53.7). All participants underwent a medical history, laboratory tests, 24-h ECG Holter monitoring, and single-night video-polysomnography (vPSG) using the American Academy of Sleep Medicine recommendations. A group of patients with diagnosed OSA was characterized by more frequent occurrence of supraventricular tachycardia (SVT) and ventricular arrhythmias (VPC). A statistically significant positive correlation was shown between the apnea-hypopnea index (AHI) and average heart rate, supraventricular arrhythmias (SVPC) pairs, SVT, and pauses &gt;2.5 s. In regression analysis, higher AHI constituted an independent predicator for the increased number of pauses &gt;2.5 s, SVT, and SVPC pairs in 24-h ECG Holter monitoring. In summary, patients with OSA are characterized by the increased number of abnormalities in 24-h ECG Holter monitoring.<\/jats:p>","DOI":"10.3390\/brainsci11040486","type":"journal-article","created":{"date-parts":[[2021,4,12]],"date-time":"2021-04-12T05:52:00Z","timestamp":1618206720000},"page":"486","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Obstructive Sleep Apnea as a Predictor of Arrhythmias in 24-h ECG Holter Monitoring"],"prefix":"10.3390","volume":"11","author":[{"given":"Dominika","family":"Urbanik","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, Borowska 213, PL 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8366-0239","authenticated-orcid":false,"given":"Pawe\u0142","family":"Ga\u0107","sequence":"additional","affiliation":[{"name":"Department of Hygiene, Wroclaw Medical University, Mikulicza-Radeckiego 7, PL 50-368 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1283-8460","authenticated-orcid":false,"given":"Helena","family":"Martynowicz","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, Borowska 213, PL 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maciej","family":"Podg\u00f3rski","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, Borowska 213, PL 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ma\u0142gorzata","family":"Por\u0119ba","sequence":"additional","affiliation":[{"name":"Department of Pathophysiology, Wroclaw Medical University, Marcinkowskiego 1, PL 50-368 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Grzegorz","family":"Mazur","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, Borowska 213, PL 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafa\u0142","family":"Por\u0119ba","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Occupational Diseases, Hypertension and Clinical Oncology, Wroclaw Medical University, Borowska 213, PL 50-556 Wroclaw, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,4,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1006","DOI":"10.1093\/aje\/kws342","article-title":"Increased prevalence of sleep-disordered breathing in adults","volume":"177","author":"Peppard","year":"2013","journal-title":"Am.
