Computer diagnosis of electrocardiograms by means of joint probability.

A study was made to establish an off-line system for the ECG diagnosis by digital computer. The joint probability was used as the main diagnostic logic, which was composed of the tailed probability. In this system, diagnoses by computer in 1392 ECG's consisted with those by physician's in more than eighty per cent. It was poined out that computer diagnoses are necessary to bring the reproducibility and accuracy in diagnosis to higher level in the various fields of the clinical medicine.
