title: Suggested minimum performance characteristics of data acquisition instrumentation in computer-assisted ECG processing systems.
abstract: The increasing importance of electrocardiogram (ECG) interpretation by computers warrants consideration of the specific technical requirements for ECG recorders used in computer-assisted ECG interpretation systems. An almost uniform characteristic of these devices is their capability to transmit the ECG signal over common carrier lines. This paper suggests minimum performance characteristics for the different components of a teletransmitting ECG recorder to facilitate the use and evaluation of computer-assisted interpretation systems. Considered are the need for signal fidelity, features for automatic quality control, and features for patient and technician safety. The performance characteristics for the ECG amplifier are only stated where they exceed the most recent recommendations of the Committee on Electrocardiography, American Heart Association. The features of the teletransmission section are based on a widely used mode and format of transmission.
