Ionizing radiation can damage an inserted electronic device, such as a pacemaker (PM) or implantable cardioverter defibrillator (ICD), if it lies in the irradiation field. Recent findings reported a possible failure of an electronic device, which lies outside the irradiation field due to scattered radiation or the production of secondary neutrons, especially when using higher photon beam energies. For this reason, new recommendations for irradiation of patients with inserted pacemakers or cardioverter-defibrillators were made.

Znano je, da ionizirajoče sevanje lahko okvari vstavljeno elektronsko napravo, kot je srčni spodbujevalnik (angl. pacemaker, PM) ali kardioverter-defibrilator (angl. implantable cardioverter defibrillator, ICD), če leži v obsevalnem polju. Nedavna odkritja pa navajajo tudi možno okvaro elektronske naprave, ki leži izven obsevalnega polja, zaradi sipanega sevanja oz. nastanka sekundarnih nevtronov, predvsem pri uporabi višjih energij fotonskega snopa. Iz tega razloga so bila izdelana nova priporočila obsevanja bolnikov z vstavljenimi srčnimi spodbujevalniki ali kardioverterji-defibrilatorji.
