When people show signs of having a heart attack an electrocardiograph (EKG) is often used to diagnose their condition. ██ █ ██████ █ ████████ ███████ ███ ███ █████████ ██ █████ ███████ ███ ██████ ███████ █ ████ ████████████ ██████ ███████ █████████████ ███ ███████ █████████ █████████ █ █████████████ ██████ ██████████ ██ ███ █████ ████ ████ █████ █████████ ██ ██ █████ ███████ ████ ███ ███ █████████████ ████████████ ███ █████ ██████████ ██████ ██ ████ ██ ████████ █████████
Summarize Argument
The author concludes that computers, rather than cardiologists, should interpret EKG data. This is because a computer outperformed a cardiologist on interpreting EKG data in a study.
Notable Assumptions
The author believes that a policy should be implemented based on an extremely limited study. She therefore assumes the sample size was adequate. She also believes that since the computer program diagnosed a higher proportion of cases that turned out to be heart attacks, the program wasn’t making some error in other cases that would compromise its function. If the computer was identifying nearly every EKG reading as a heart attack, its value would be extremely limited.
