Abstract:
1. A method of detecting ischemia during exertion, comprising: executing non-transitory machine-executable instructions stored in memory for; obtaining static exertion measurements indicative of static physiological exertion; identifying steady state periods of physiological exertion based on the static exertion measurements; assessing the intensity of physiological exertion for each of the identified steady state periods; sensing extra-cardiac response data during identified physiological exertion steady state periods; sensing cardiac response data during identified physiological exertion steady state periods; comparing the extra-cardiac response data corresponding to identified steady state periods of physiological exertion with extra-cardiac response information associated with equivalent physiological exertion intensity; determining the normalcy of the extra-cardiac response data for each steady state period based on the comparison of the extra-cardiac response data and the extra-cardiac response information; comparing the cardiac response data corresponding to identified steady state periods of physiological exertion with cardiac response information associated with equivalent physiological exertion intensity; determining the normalcy of the cardiac response data for each steady state period based on the comparison of the cardiac response data and the cardiac response information; and determining the likelihood that myocardial ischemia occurred during one or more of the identified steady state periods of physiological exertion, wherein:
