A magnet does not always switch the pacemaker off. For pacemakers that are vital, the magnet usually switches to a safe mode, e.g. some fixed non-adaptive frequency and voltage. Frequency and voltage are chosen in a way that the patient will not suffer injury from it and have sufficient circulation to survive. However, due to the necessary higher frequency and pressure when standing up, walking, those things will lead to weakness, fainting, dizzyness and all the other symptoms of low blood pressure. Safe mode will keep you alive, but it definitely won't be fun.
- lmilcin 5y agoI have to use simplified language sometimes to get the point across. I could write all day how I work with electronics, have my own laboratory, what the EMI is and why exactly magnet is not one, but by the time I would get to the point most readers would already either fall asleep or would just look at the huge article and skip to another post. Yes, pacemakers became more complex devices but at least the older ones work as I described and for the newer ones it is enough approximation. It is not like you can do anything else or anything different if one misbehaves.
