It is diagnosed in the presence of excessive daytime sleepiness and an apnoea\u2013hypopnoea index (AHI) of \u22655 on polysomnography. Rhythm disturbances are common in OSAS and continuous positive airway pressure (CPAP) has been shown to be beneficial. We present a case of a patient with obesity, atrial fibrillation with fast ventricular response, significant nocturnal pauses (3.9\u2005s) and tachycardiomyopathy. A polysomnography confirmed severe OSAS (AHI=64.25). CPAP improved bradycardia and allowed for the introduction of \u03b2-blockers. Subsequent Holter monitoring revealed better rate control with the longest pause of 2\u2005s and the patient's left ventricular systolic function improved. CPAP prevented our patient from invasive treatment, allowed for rate control and improvement of tachycardiomyopathy. With such a high prevalence of OSAS, clinicians should be aware that CPAP may aid arrhythmia control.<\/jats:p>","DOI":"10.1136\/bcr-2014-208112","type":"journal-article","created":{"date-parts":[[2015,4,1]],"date-time":"2015-04-01T09:58:59Z","timestamp":1427882339000},"page":"bcr2014208112","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Treatment of tachycardia: bradycardia syndrome in a patient with obstructive sleep apnoea"],"prefix":"10.1136","volume":"2015","author":[{"given":"Jakub","family":"Lagan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Palaniappan","family":"Saravanan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2015,4,1]]},"reference":[{"key":"2025042705514950000_2015.apr01_1.bcr2014208112.1","unstructured":"Scottish Intercollegiate Guidelines Network.
