Computer evaluation of spirometric examinations and electrocardiograms.

Computers experiences ever increasing possibilities in acquisition and evaluation of biosignals both for the experimental and practical application within the scope of executive health care institutions. The analysis and evaluation of biosignals on a computer is time-saving, and can involve quantitative parameters as well as mathematical methods which in the absence of computer techniques would be unmeasurable in practice. The paper describes the basic approaches to the solution of analysis automation, and to the computer evaluation of spirometric examination and ECG as proposed at the Research Institute of Medical Bionics in Bratislava. The technical and program system for evaluation of forces expiration within the scope of spirometric examinations and two systems of ECG evaluation are described. The first system utilizes the standard 12-lead ECG and Minnesota code, the second system processes vector-cardiogram derived from Frank's orthogonal leads under application of Pipberger's program.
