Safety of Smartphones Among Patients With Cardiac Implantable Electronic Devices

Over the past year smartphones have developed from a niche product to a commoditized product and are now squeezing classic mobile phones out of market. According to a survey a quarter of the German population is making use of a smartphone at present. An interference between smartphones and the functionality of pacemakers or implantable defibrillators is rather unlikely but cannot entirely be excluded. A systematic study regarding a possible interference between smartphones and modern pacemaker- and ICD-system with a better shielding against external influence has not taken place so far. In this study the investigators intend to investigate any interference between different smartphones produced by different manufacturers and diverse cardiovascular implanted electronic devices.
