The design, development, and implementation of a microprocessor-based ECG analysis system

Abstract

This paper describes the research effort to design, develop, and implement a microprocessorbased ECG data acquisition, reduction, and analysis system for operation in real-time. This unit can be attached to three-channel ECG carts and provide an immediate on-site analysis. The basic design and development efforts include (1) the data acquisition, reduction, and matrix assembly, (2) ECG arrhythmia, P-wave, and axis analysis, (3) ECG contour analysis, and (4) a real-time three-channel data acquisition unit. Decision tables are used in the analysis. The implementation of these projects into a small microprocessor-based unit coupled to a three-channel recorder is now in progress. This system, coupled with a small printer, will provide immediate on-site ECG analysis for most cardiovascular dysfunctions.

Computerized service delivery in clinical psychology.

“…On-line data collection by computer is common in behavioral medicine, especially in psychophysiological treatment and research. Examples include on-line monitoring and analysis of electrocardiograms (Murray, 1982) and electroencephalograms (Bremner, Yost, & McKenzie, 1982). The literature on the development and use of computerized techniques in this area is voluminous and, therefore, beyond the scope of this article.…”

ECG Signal Analysis

“…Later on, in the 1970s, microprocessor standalone units were in use for automated interpretation. In [65], use of a microcomputer-based 3-channel ECG analysis system for P wave, arrhythmia, and axis analysis is described. In [66], a time-domain morphology and gradient-based algorithm is presented.…”
