Re: Can a magnet damage your heart?

That's an interesting question.

There is really good evidence that exposure to magnetic fields, even very strong ones, had little or no effect on human organ functions in general, including the heart. One of the moost effective diagnostic imaging devices, the magnetic resonance imager (MRI), uses very strong magnetic fields - much stronger than a permanent magnet - to probe the human body.

According to cardioligists with whom I've spoken, nearly all people experience at least one bout of arhythmia in the course of their lives, and up to a quarter of some populations have some kind of chronic arhythmia though most do not realize it until it turns up while their physician looking for something else. So, while it's not possible to state for certainty as I am not your physician, it's pretty likely that there is no correspondence between your exposure to the magnet and the arhythia your doctor found.
