HEART DEVICE
Researchers investigating a new version of electrical defibrillation for
the treatment of atrial fibrillation (AF) believe that a series of lower
energy electrical shocks would be less painful and carry less risk of
complications than the short, sharp electrical shocks currently used to
resynchronize a patient's heart beat. AF is a condition that often leads
to heart failure and stroke.
To test the concept, the team designed and built a device that gets implanted
under the skin close to the heart. Sensors on the cardiac telemetry system
pick up the heart's electrical pattern and send out a continuous radio signal,
which is picked up by a notebook computer fitted with a receiver. This set up
allows an electrocardiogram to be directly recorded on to the computer without
external sensors and wiring.
In return, the computer can send a signal back to the device telling it to
deliver a short burst of electrical pulses directly to the heart. The sensors
measure the effect on the heartbeat and send the data back to the computer.
