Abstract
An ECG analysis system is responsive to patient ECG data for performing an analysis of the ECG data to determine whether acute MI is present. The system first analyzes the ECG data by standard ECG analysis to determine whether acute MI is present. This analysis is followed in a first mode of operation by ACI-TIPI analysis to estimate the probability of acute MI from patient characteristics and the ECG data. In a second mode, when the standard ECG analysis is definitive as to the presence of acute MI the ACI-TIPI analysis is not run and the user is presented with only the results of the standard interpretation. If the standard ECG analysis is indeterminate as to the presence of acute MI, then the ACI-TIPI analysis is run and the results of the ACI-TIPI analysis are presented to the user.
Claims13
An ECG analysis system which analyzes patient ECG data comprising:
- a standard ECG analysis processor adapted to analyze ECG data to produce a result output indicating whether a myocardial infarction (MI) is indicated;
- an ischemia predictive indicator processor, responsive to patient characteristic data, and adapted to analyze patient characteristic data and ECG data to produce a result output indicating the probability of a myocardial infarction;
- and
- a processor sequence setting by which operation of the ischemia predictive indicator processor is conditioned upon the result output of the standard ECG analysis processor,
- wherein the processor sequence setting prevents the ischemia predictive indicator processor from presenting its result output to a user in direct response to the processor sequence setting determining that the result output of the standard ECG analysis processor indicates that acute MI is present or in direct response to the processor sequence setting determining that the ECG is normal.
A method for analyzing patient ECG data comprising:
- analyzing ECG data with a standard ECG analysis processor to produce a result output indicating whether a myocardial infarction (MI) is indicated;
- and, conditioned upon the result output of the ECG data analyzing by the standard ECG analysis processor,
- analyzing patient characteristic data and ECG data with an ischemia predictive indicator processor to produce a result output indicating the probability of a myocardial infarction;
- and
- visually presenting one or more result outputs,
- wherein analyzing with the ischemia predictive indicator processor is inhibited in direct response to the processor sequence setting determining that the result output of the standard ECG processor indicates that the ECG is normal.
