Cardiac involvement occurs in only 1% of untreated patients. We describe the case of a 46-year-old man who presented with chest pressure, dyspnoea, palpitations and syncope. He presented initially with atrial fibrillation with rapid ventricular response, a rare manifestation of Lyme carditis. In another hospital presentation, he had varying degrees of atrioventricular block including Mobitz I second-degree heart block. After appropriate antibiotic treatment, he made a full recovery and his ECG normalised. The authors aim to urge physicians treating patients in endemic areas to consider Lyme carditis in the workup for patients with atrial fibrillation and unexplained heart block, as the associated atrioventricular nodal complications may be fatal.<\/jats:p>","DOI":"10.1136\/bcr-2018-228975","type":"journal-article","created":{"date-parts":[[2019,4,29]],"date-time":"2019-04-29T09:06:49Z","timestamp":1556528809000},"page":"e228975","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":9,"title":["Lyme carditis presenting as atrial fibrillation"],"prefix":"10.1136","volume":"12","author":[{"given":"Abir","family":"Zainal","sequence":"first","affiliation":[{"name":"Department of Internal Medicine, Unity Hospital, Rochester, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amir","family":"Hanafi","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Unity Hospital, Rochester, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ninad","family":"Nadkarni","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Unity Hospital, Rochester, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahmood","family":"Mubasher","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Unity Hospital, Rochester, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Deeraj","family":"Lingutla","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, Unity Hospital, Rochester, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Hoefen","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Rochester Regional Health, Rochester, New York, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2019,4,29]]},"reference":[{"key":"2025082801560044000_12.4.e228975.1","unstructured":"CDC.
