Precautions for users of implanted cardiac pacemakers
Cardiac pacemakers (applies only to digital cordless devices):
Wireless Technology Research, LLC (WTR), an independent research entity, led a
multidisciplinary evaluation of the interference between portable digital cordless
devices and implanted cardiac pacemakers. Supported by the U.S. Food and Drug
