Kim Zolciak -- No Show Tonight on 'Dancing With the Stars'

Kim Zolciak will not appear on Monday night's episode of "Dancing with the Stars," because she's unable to leave Atlanta after her medical emergency ... TMZ has learned.

As we reported, Kim flew back to Atlanta after last week's show and almost immediately went into the hospital ... she says because of a mini-stroke. We're told she had a heart procedure Friday and was released, but doctors advised her not to do anything strenuous or travel.

We're told Kim will appear on the show via FaceTime. Her long-term prognosis on the show is uncertain.
