Abstract
A method for generating a cardiac electrical instability assesment is disclosed herein. The method includes obtaining a SDTWA measurement, obtaining a LDTWA measurement, and obtaining a cardiac electrical instability assessment based on both the SDTWA measurement and the LDTWA measurement.
Claims20
A method comprising:
- obtaining a SDTWA measurement;
- obtaining a LDTWA measurement;
- and
- obtaining a cardiac electrical instability assessment based on both the SDTWA measurement and the LDTWA measurement.
1 more element
A method comprising:
- obtaining a SDTWA differential measurement;
- obtaining a LDTWA differential measurement, said obtaining a LDTWA differential measurement comprising eliminating any data exceeding a first high differential limit from the LDTWA measurement;
- diagnosing electrical instability if the SDTWA differential measurement exceeds a second high differential limit or if the LDTWA differential measurement exceeds a low differential limit;
- and
- performing a TWA burden analysis in order to obtain a degree of concern assessment.
2 more elements
A system comprising:
- a plurality of sensors;
- and
- a processor operatively connected to the plurality of sensors, said processor configured to generate a cardiac electrical instability assessment based on a SDTWA measurement and a LDTWA measurement.
