US Vice President Dick Cheney has been found to have an irregular heartbeat and will get further evaluation shortly, his spokeswoman has said.
[...] Mr Cheney, 66, has had four heart attacks, quadruple bypass surgery and operations to clear blocked arteries. He was fitted with a pacemaker in 2001.
In July, the vice president had minor surgery to replace the pacemaker’s battery which was running low.
Mr Cheney has also had operations to clear blood clots in his knees and in March started taking blood-thinning medicine to treat another blood clot in his lower left leg.
