US Vice president to have minor surgery for new battery in heart device

Vice President Dick Cheney is undergoing a minor surgical procedure Saturday to replace the battery

that powers a device monitoring his heart rhythms.

During Cheney's annual physical last month, doctors tested his implanted cardioverter-defibrillator and learned that its battery had reached a level where replacement is recommended, Megan McGinn, Cheney's deputy press secretary, said Friday. (AP)
