Dr. T. Allan Pryor, associate professor of biophysics and computing in the University of Utah College of Medicine, was the first researcher in the world to pablish a program for computerized interpretation of electrocardiograms in light of previous ECG's on that patient "Each person is a little different so we can never replace the human judgment that goes into such an analysis," emphasizes Pry or, "but automated interpretation of ECG's adds another level of confidence. The physician and computer together make a better reader than either does atone." In recent studies, a board of review physicians agreed with the ' 1 computerized ECG analysis up to 90 percent of the time. "That compares very favorably with the group's agreement with individual cardiologists' diagnoses when the same review criteria is applied to the computer," Pryor notes. "We have broad experience in this area because more than four million ECG's are computerized annually." Dr. Frank Yanowitz, assistant professor of cardilogy in the College of Medicine and director oof the LDS Hospital Exercise Lab, says the automated ECG system is a great time-save- r. "The computer takes flF ILGQ(3Ii Pew o mil o SpeoQUDsGn l?rfi g 'jfjpf Q0t7 jj L7WQg( bSQ away the burden of reading tons of ECG's.

"These very sensitive tests can indicate the slightest deterioration in a given patient's ECG," say3 Pryor. "These slight changes in wave patterns may not be considered abnormal in a single tracing but they may be diagnostic when compared against a previous reading.
