Key result
Mediastinal radiotherapy was safely delivered to a patient with an implanted cardiac pacemaker by restricting the cumulative dose to the pacemaker to 1.15 Gy, maintaining normal pacemaker function at 2.5 years follow-up.
Why the study?
Delivering radiotherapy to patients with implanted pacemakers is challenging when treatment portals are close to the pacemaker, requiring cumulative doses below 2 to 5 Gy.

Radiotherapy can be safely delivered to patients with cardiac pacemakers by following a structured algorithm to keep the cumulative dose to the device below 2 Gy.
Sidhique et al. (2022) conducted a case report in Classical Hodgkin's Lymphoma and implanted cardiac pacemaker (n=1). Mediastinal radiotherapy was evaluated on Cumulative radiation dose to the pacemaker and pacemaker function. Mediastinal radiotherapy was safely delivered to a patient with an implanted cardiac pacemaker by restricting the cumulative dose to the pacemaker to 1.15 Gy, maintaining normal pacemaker function at 2.5 years follow-up.
