Automated Cardiac Status Determination System |
摘要 |
A system fits a curve to a filtered ECG signal, processes the fitted curve (e.g., by applying transforms such as a KL Transform) and derives parameters for use in classifying heart cycle signal portions (such as an ST segment portion) into particular heart cycle signal portion categories associated with particular segment morphology. A system for heart signal classification includes an interface for receiving an electrical signal waveform comprising an R-wave and including an ST segment portion associated with heart electrical activity of a patient over a heart beat cycle. A signal processor processes data representing the electrical signal waveform by fitting a curve to the ST segment and applying a transform to the fitted curve to derive variance data indicating variance in the fitted curve. A signal classifier classifies the ST segment into one of multiple predetermined categories associated with the fitted ST segment curve geometry in response to the derived variance data.
