US vice president Dick Cheney was taken to George Washington Hospital in Washington early today experiencing shortness of breath, a spokeswoman said.
Lea Anne McBride said that doctors found his EKG unchanged and determined he was retaining fluid because of medication he was taking because of a foot problem.
Cheney, who has a history of heart problems and has a pacemaker in his chest, was placed on a diuretic.
McBride said the vice president was expected to be released from hospital later today.
A foot ailment forced Vice President Dick Cheney to use a cane on Friday.
