Any danger in 91 y/o with icd defib. Using a 2 way radio "walkie talkie? " I'm just concerned b/c not sure if the radio waves could harm the icd at all

ICD and radios. There have been no reported problems with radios and icd's, however, to be safe would use the walkie talkie on the side opposite the implanted device. The same is true for cell phones.
Radio. The sensors for the defibrillator are embedded in the heart. A radio will not affect the device.
