Executive summary

A study by Heidelberg group looked into if ionizing radiation influenced the function of cardiac implantable electronic devices (CIED's) leading to malfunctions with potentially severe consequences. 31 patients (22 received treatment with carbon ion and 10 with proton) were analyzed, among whom 3 patients had an implantable cardioverter-defibrillator (ICD) and 28 patients had a pacemaker at the time of treatment.

The cumulative number of fractions was 582 and the cumulative number of documented controls after RT was 504.

This analysis reported that treatment of CIED-patients with protons and carbon ions was safe without any incidents.
