D. A Watchful Eye On Heart Attack Patients

Narrator: This is Science Today. An attachment which converts a three view electrocardiogram into a detailed 12-view picture of the heart is in development. Barbara Drew, a professor at the School of Nursing at the University of California, San Francisco says this simple, non-invasive monitoring of heart attack patients is welcome in this day and age.

Drew: There's a huge pressure to get patients out of the hospital as soon as possible and we feel that this very detailed way of monitoring patients is one way to be safer about letting people go early because we know if our very accurate monitoring system has been quiet overnight, then it's probably safe to say the patient can go home early.

Narrator: Drew says HMOs would also appreciate this system.

Drew: If you can better separate the high risk from the low risk and let the low risk go home and keep just the high risk, then I think that's more cost effective.

Narrator: For Science Today, I'm Larissa Branin.
