What are the noises coming from a heart device?
If a heart device is beeping or vibrating, it means either the device has detected something that a doctor should look at or there is possible magnetic interference. If a magnet is causing these actions, move a safe distance away. If this continues, it could be a major item for a doctor to review or it could be as minimal as a simple change in measurements. Call the clinic and ask for instructions, whether that is an in-person visit or a manual transmission of device data.
