Wireless World: Wirelessly monitoring ECGs

An elderly woman has a heart attack. Paramedics arrive on the scene at her home a few minutes later and begin to revive her, and hook up an electrocardiogram transmitter to her chest, and send the signals, wirelessly, to a cardiologist at the hospital, who reads the vital signs on a handheld device. That technology advance is now saving lives, experts tell United Press International's Wireless World. And it's just one of the ways hospitals are today innovatively using wireless devices.
