hey surgical hrt rn,
in no way does one need ekg certification (which, imo, means nothing unless you even remotely become proficient in not only knowing the geography of reading an ekg, but knowing and understanding axis deviation, r-r', qtc, etc...) to work in the icu. what one learns in acls is more than adequate to recognize the two main lethal arrythmias, vt and vf.
also, can you reference the legality of "reading" an ekg without certification? jcaho?? c'mon, they aren't even clinicians that run the commission, so i don't hold much water for them.
and also again, even if you "read" the ekg, chances are the md will be making the ultimate decision.
so, in short, i disagree with what you say re: 12 lead certification.
