We report a case of a 40-year-old woman with a recent gastric sleeve surgery, who presented with symptomatic sinus bradycardia following significant post-surgical weight loss. Extensive workup excluded common causes such as electrolyte disturbances, hypothyroidism, or cardiomyopathy. We hypothesize that alterations in leptin metabolism due to weight loss triggered increased vagal stimulation, leading to her bradycardia. The patient was treated with theophylline as a noninvasive alternative to pacemaker implantation. Long-term monitoring showed partial improvement in heart rate. This case highlights the need for vigilance in managing bradycardia as a potential side effect of bariatric surgery-induced weight loss, emphasizing the importance of follow-up and the potential role of leptin in heart rate regulation. <\/jats:p>","DOI":"10.1177\/2050313x251321063","type":"journal-article","created":{"date-parts":[[2025,2,19]],"date-time":"2025-02-19T12:24:41Z","timestamp":1739967881000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Sinus node dysfunction following bariatric surgery: A case report"],"prefix":"10.1177","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-6988-0934","authenticated-orcid":false,"given":"Kristoffer","family":"Dahl","sequence":"first","affiliation":[{"name":"Cardiology Department Bodo, Nordlandssykehuset, Bodo, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9976-7791","authenticated-orcid":false,"given":"Knut Tore","family":"Lappegard","sequence":"additional","affiliation":[{"name":"Cardiology Department Bodo, Nordlandssykehuset, Bodo, Norway"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,2,19]]},"reference":[{"key":"bibr1-2050313X251321063","unstructured":"Glikson M, Nielsen JC, Kronberg MB, et al. 2021 ESC Guidelines on cardiac pacing and cardiac resynchronization therapy: Developed by the Task Force on cardiac pacing and cardiac resynchronization therapy of the European Society of Cardiology (ESC) With the special contribution of the European Heart Rhythm Association (EHRA), https:\/\/academic.oup.com\/eurheartj\/article\/42\/35\/3427\/6358547?login=false (2021, accessed 15 April 2024)."},{"key":"bibr2-2050313X251321063","unstructured":"Norwegian Directorate of Health.
