I'm trying to think of examples where using an anti-alias filter is a
bad idea, or must at least be approached with extreme caution. I
already know about control systems and video applications, and I believe
that this is a big issue with EKG machines.

Does anyone else have any examples that they can share?

If someone has a sampled EKG output in some readable file format that
they'd be willing to share I would be grateful -- I can whomp something
up out of nothing, but then some doctor will read my article and know
it's BS.
