(WHITE HOUSE, AP, June 29th, 2001, 11:35 a.m.) -- The heart test that Vice President Cheney will undergo Saturday is similar to an internal electrocardiogram.
Wires with electrical sensors are threaded through veins to the heart. The wires then give readings on the functioning and rhythm of the heart muscles -- and help spot any problems in the heart's beating rhythm.
Cheney told reporters Friday that he has been experiencing irregular heart rhythms. He says he expects Saturday's tests will lead to the implant of a pacemaker to restore normal rhythm.
Cheney says his condition should not inhibit his ability to do his job.
