Vice President Cheney checked himself into George Washington Hospital for a repeat cardiac catheterization after experiencing two brief, mild episodes of chest discomfort. This is a non-emergency precautionary procedure. An EKG obtained at the White House this afternoon was unchanged from one obtained last Thursday.
