Medtronic has analyzed iPhone technology and found that it presents no increased risk of interference with Medtronic implantable cardiac rhythm devices, such as pacemakers, implantable defibrillators (ICDs), and cardiac resynchronization therapy defibrillators (CRT-Ds), when used according to labeling.

As a precaution, we advise patients implanted with cardiac devices to maintain a distance of six inches (15 cm) between all cell phones and their implanted devices, consistent with recommendations for other low wattage electromagnetic devices. 

Recent studies did not follow this advice or the approved labeling for these devices in their methodology. When used as directed, there is no increased risk of interference.

To protect our patients, we have built safeguards into Medtronic implantable cardiac devices to allow for normal daily interference; these safeguards include electronic filters that distinguish between natural heartbeat signals and other potential interference.
