Validity of computer interpretation of the electrocardiogram

Evaluation of the accuracy of computer interpretation of 2019 standard 12-lead ECG's has been carried out. In 762 records defined as normal by the cardiologist the computer agreed in 41%, found 49% with minor "abnormalities" and read 10% as having gross abnormalities.There were 1257 abnormal records. The computer read 43 of these as normal including five with infarction and three with LVH. Agreement in the various abnormal categories ranged from 31% to 85% and even after review disagreement remained in 33% of cases.
