A man in his 60s with a history of heart transplantation with biatrial anastomosis 7 months prior presented to the emergency department after several syncopal episodes. Telemetry monitoring revealed a paroxysmal complete atrioventricular block. Given his immunocompromised state and prior dual chamber pacemaker extraction at the time of heart transplantation, the patient underwent successful implantation of a leadless pacemaker. Over the past 5 years since device implantation, the patient has not had any syncopal events nor has he had any device-related complications, such as infection.<\/jats:p>","DOI":"10.1136\/bcr-2023-256054","type":"journal-article","created":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T13:40:36Z","timestamp":1694439636000},"page":"e256054","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Leadless
