A spokeswoman says medical tests performed on U.S. Vice President Dick Cheney have revealed a minor problem with his esophagus and some dilation of the arteries behind his knees.
Cheney spokeswoman Lea Anne Mcbride says the tests were performed Saturday as part of the vice president's annual medical checkup.
Ms. McBride says Mr. Cheney was diagnosed with a minor case of esophagitis, an inflammation of the esophagus usually associated with heartburn or acids in the stomach.
She said vascular screening revealed small, widened segments of arteries behind both knees.
Mr. Cheney underwent the first part of the medical exam July eighth. Those tests revealed no problems with the pacemaker he received in 2001 following a heart attack.
