Cheney Gets Clean Bill Of Health

Vice President Dick Cheney received a clean bill of health Friday after a routine cardiovascular exam, the White House said.

Spokeswoman Mary Matalin said that Cheney's doctor, Jonathan Reiner, reported that the vice president's high-tech pacemaker "continues to function flawlessly and has not detected nor treated any arrhythmia."

The device, implanted in Cheney's chest in June 2001, is designed to monitor his heart and if necessary adjust its rhythm.

Matalin said after the exam, Cheney returned to his normal workday outside the White House. Cheney has been staying at a secure undisclosed location since President Bush put the nation on high alert earlier this week. Matalin said Reiner reported that Cheney will "continue to live a vigorous lifestyle."

Cheney has had four heart attacks, none as vice president.
