Chest pains send Cheney to hospital
Former U.S. vice-president Dick Cheney has checked into a hospital in Washington, D.C., after experiencing chest pains, an aide said.
Cheney's assistant, Peter Long, said in a statement late Monday that the 69-year-old Cheney was resting comfortably at the George Washington University Hospital and his doctors were evaluating the situation.
Cheney has a history of heart problems and wears a pacemaker.
In 2008, doctors restored a normal rhythm to his heart with an electric shock. It was the second time in less than a year that Cheney had experienced and been treated for atrial fibrillation, an abnormal rhythm involving upper chambers of the heart.
Cheney has had four heart attacks, starting when he was 37. He has had quadruple bypass surgery and two artery-clearing angioplasties.
