Abstract

A method and apparatus for dynamically estimating the ST segment of a rate varying electrocardiogram by comparing the result yielded from a mathematical relationship between calculated beat averages and a predetermined standard. Typically a table of known heartbeats is made from which means for estimating are created. An average of beat to beat intervals is compared with the means for estimating and the length of the ST segment for any particular beat is derived making it possible to dynamically alter ST segment length for any given heartrate.
