[Are pectoral implanted cardioverter defibrillators subject to electromagnetic interference by D-net mobile-phones].

: The use of GSM or D-net mobile-phones has been proven to disturb antibradycardiac pacemaker function by electromagnetic fields. Therefore interference between these phones and subpectroral ICD-systems is conceivable. We investigated effects on programmed parameters, sensing and pacing, as well as detection and termination of arrhythmias in 15 patients with pectoral single-lead ICD-systems (Cardiac Pacemaker Inc., Ventak PRX III and Ventak Mini). During all tests, including stand-by mode, incoming and outgoing calls and transmission, no malfunction of the ICDs occurred. In conclusion, the use of a D-net mobile phone (European GSM-standard) by patients with subpectoral ICD-systems of the tested types seems to be safe.
