Although recognised among high-level endurance athletes, this case demonstrates the potential negative effects of exercise on the heart in a patient participating in the levels of exercise recommended by Public Health England. It adds weight to the ongoing discussion of the incomplete understanding of the level of exercise needed to induce pathological changes in cardiac physiology. We discuss the investigations that led us to our diagnosis, highlighting the importance of a detailed exercise history in patients who present with palpitations and provide a potential explanation of how this phenomenon may have occurred. Currently, bradycardia induced by exercise has been managed through pacemaker insertion or complete cessation of exercise. This report demonstrates effective treatment through a period of exercise cessation and slow reintroduction of exercise training.<\/jats:p>","DOI":"10.1136\/bcr-2021-246333","type":"journal-article","created":{"date-parts":[[2021,12,8]],"date-time":"2021-12-08T11:52:03Z","timestamp":1638964323000},"page":"e246333","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Symptomatic second-degree atrioventricular block in a recreational athlete"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7952-5963","authenticated-orcid":false,"given":"Manisha","family":"Gandhi","sequence":"first","affiliation":[{"name":"Cardiology, Department of Medicine, Northumbria Healthcare NHS Foundation Trust, North Shields, UK"},{"name":"Cardiology, Department of Medicine, Imperial College Healthcare NHS Trust, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Honey","family":"Thomas","sequence":"additional","affiliation":[{"name":"Cardiology, Department of Medicine, Northumbria Healthcare NHS Foundation Trust, North Shields, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,12,8]]},"reference":[{"key":"2025082800243107000_14.12.e246333.1","unstructured":"Public Health England .
