Errors of Computer Electrocardiography.

A review of 6938 computer-generated electrocardiogram interpretations was undertaken by a single cardiologist. The computer-assisted program correctly interpreted 51.6% of the tracings. One or more corrections were necessary in 48.4%. The greatest number of incorrect interpretations involved repolarization (T wave) abnormalities, followed by ST segment changes. It is mandatory that computer-generated ECG interpretations be reviewed by an experienced electrocardiographer. Reliance on nonreviewed ECG interpretations may result in incorrect diagnoses that could lead to inappropriate management decisions. [ABSTRACT FROM AUTHOR]
