First Claim
Patent Images
1. An apparatus comprising:
- an activity sensor circuit, configured to receive an activity signal indicative of physical activity of a subject during the subject'"'"'s activities of daily living;
a physiological sensor circuit, configured to receive a concurrent actual physiological response signal, different from the activity signal, during the subject'"'"'s activities of daily living;
a signal processor circuit, configured to generate an approximate physiological response signal, including;
convolving the activity signal with a template for generating the approximate physiological response signal, the template including at least one characteristic parameter; and
comparing information from the approximate physiological response signal with information from the actual physiological response signal to determine the at least one characteristic parameter; and
wherein the signal processor circuit is configured to provide information from the at least one characteristic parameter to a user or process.

Abstract
A physiological response to activity (PRA) during a subject'"'"'s activities of daily living (ADL) can be used, such as to generate useful diagnostic information about the subject. This can involve using a template, such as an impulse response template. The technique can be used with an implantable or other ambulatory medical monitoring or therapy device, such as a cardiac function management device, or with a local or remote external interface device.
