Abstract
An implantable cardiac device detects a progression or regression in heart disease such as congestive heart failure. An activity sensor and a respiration sensor generate raw signals indicative of the patient'"'"'s activity level and respiration level. Degradation or improvement of the patient'"'"'s activity and respiration over a predetermined time corresponds to an indication of the progression or regression of the heart disease. A processor coupled to the sensors is programmed to process the raw sensor signals over the predetermined time and stores the processed sensor signals in a memory having a data storage area. A telemetry circuit coupled to the memory is configured to transmit the stored sensor signals to an external monitor for subsequent display. The processor further controls pacing of the heart, adjusts pacing therapy responsive to the process signals, and process the raw respiration signals when the patient is in a number of different active states.
