When people show signs of having a heart attack an electrocardiograph (EKG) is often used to diagnose their condition  In a study, a computer program for EKG diagnosis of heart attacks was pitted against a very experienced, highly skilled cardiologist  The program correctly diagnosed a significantly higher proportion of the cases that were later confirmed to be heart attacks than did the cardiologist
Interpreting EKG data, ttherefore, should be left to computer programs
The cardiologist correctly diagnosed a significantly higher proportion of the cases in which no heart attack occurred than did the computer program.
