Vice President Cheney Briefly Hospitalized
The vice president left the hospital after about four hours, aides told CNN.
Cheney spokeswoman Lea Anne McBride said that physicians found his EKG unchanged and diagnosed he was retaining fluid because of medication he was taking due to a foot problem, the Associated Press reports. On Friday, that ailment forced Cheney to use a cane.
McBride said the vice president was placed on a diuretic before being released.
Cheney, who turns 65 at the end of this month, has a history of heart problems and has a pacemaker in his chest.
