Cheney's heart returns to normal | |
(about 6 hours later) | |
US Vice-President Dick Cheney has successfully undergone treatment to correct an abnormal heart rhythm, his spokeswoman has said. | |
Mr Cheney, 67, received an electric impulse which was administered without complication at the George Washington University Hospital. | |
He later resumed his normal schedule, but was forced to cancel a planned political event in Illinois. | |
Mr Cheney has had four heart attacks and quadruple bypass surgery. | |
He has undergone several operations to clear blocked arteries and was fitted with a pacemaker seven years ago. | |
"During a visit with his doctors this morning, it was discovered that the vice-president is experiencing a recurrence of atrial fibrillation, an abnormal rhythm involving the upper chambers of the heart," said the spokeswoman, Megan Mitchell. | |
"An electrical impulse was delivered to restore the heart to normal rhythm," Ms Mitchell added later. | |
