JACC Case Rep. 2020 Feb 19;2(2):240-244. doi: 10.1016/j.jaccas.2019.11.077. eCollection 2020 Feb.


We highlight a diagnostic challenge in a patient with dyspnea on exertion due to radiation therapy-induced severe first-degree atrioventricular block and how permanent His bundle pacing was helpful in overcoming these symptoms. (Level of Difficulty: Intermediate.).

Keywords: AV, atrioventricular; ECG, electrocardiography; HB, His bundle; HBP, His bundle pacing; RBBB, right bundle branch block; RV, right ventricular; cardiac pacemaker; cardiac resynchronization therapy; electroanatomic mapping; electrocardiography; electrophysiology; shortness of breath.
