I've done a cursory look into a pacemaker's "magnet mode."
Note: I have no idea what I'm talking about, so take all of this as pure, unadulterated guesswork. I don't know which model pacemaker Nancy has or her specific heart condition. Hopefully, we can get someone with pacemaker/cardiac knowledge to comment here.
Resource info for magnet mode:
Medtronic Academy
Some possible salient quotes from the above source:
- "A magnet over a Medtronic pacemaker causes the pacemaker to... Switch to an asynchronous mode"
- "The pacemaker automatically suspends all diagnostic data collection while a magnet is applied to the pacemaker."
- "Positioning a magnet over a Medtronic ICD suspends tachyarrhythmia detection"
- "When the magnet is removed, the ICD resumes tachyarrhythmia detection and therapy delivery as programmed."
- "A steady tone emits for 10 seconds when a magnet or the programming head is applied over the device to verify that notifications are operational and no alert conditions are met." (Note: I've read elsewhere this doesn't apply to all models.)
What I'd like to know is: 1) Does it disable the bluetooth connection? 2) Do pacemakers alert/report magnet mode to the phone, and if so, is there a delay? 3) Would a racing heart due to extreme fear usually trigger a pacemaker alert, and would that then trigger some sort of medical emergency flag?
