Radiation Resistance in Modern Pacemakers

Device Design and Functionality

• The use of enhanced battery technology and generator design has increased device longevity and reliability overall, allowing for greater programmability and telemetry capabilities that enable real-time monitoring and adjustment during radiation exposure, as noted by the American Heart Association, based on research published in Circulation 1

Clinical Implications and Precautions

• The American Society of Anesthesiologists recommends that devices be positioned outside the radiation field, with surgical relocation performed if necessary before commencing radiation therapy, and verification of pulse generator function during and at completion of radiation therapy is also recommended 2
