Why the study?

Does photon irradiation cause pacemaker failure in patients with pacemakers?

Population

1 patient with a pacemaker and metastatic bronchogenic carcinoma

Design

Case_report

Authors

Discussion

Photon irradiation at 20 Gy may cause pacemaker runaway; case report leaves open prospective validation of device tolerance limits.

Does photon irradiation cause pacemaker failure in patients with pacemakers?

Population

1 patient with a pacemaker and metastatic bronchogenic carcinoma

Intervention

2,000 rad (20 Gy) of photon irradiation

Outcome

Pacemaker failure (pulse generator circuitry failure producing a 'runaway' rhythm)safety

Modest radiation doses can induce life-threatening arrhythmias due to pacemaker circuitry failure.

Quertermous et al. (1983) studied this question.
