Some early AI systems for ECG interpretation and serum protein electrophoresis analysis were deployed clinically and remain in use.

“there were applications of medicine back then that survived till today for example already back then we had these systems doing interpretation of ECGs um uh actually pretty competently um at least a first pass until they would be reviewed by an expert cardiologist so that was uh there's also a program that interpreted um what's called serum protein electroforesis where you look at the proteins separated out by an electric gradient to make a diagnosis let's say of Myoma or other protein disorders and those also were deployed clinically but they only worked very much in narrow areas”
