Why is the training MD->IM->Cardiology->EP, rather then MD->IM-
>Cardiology->Intvl. Cardiology ->EP?

And, what type of arrythmia would the ER doc find too complex and/or
not equipped to handle alone, so a page to EP is necessary.

And, I know the cathethers are guided by fluoroscopy, but how does the
electrophysiologist thread the cathether from the leg to the heart; by
pushing on it? I know the new EP labs have magnets draw the catheter
along, and use a joystick to control magnets which navigate it, but
how did they do this in the old labs that aren't stereotaxic?
