Abstract
In an implantable cardiac device data is processed and stored to conserve storage space and computational resources thereby saving energy expended on these operations. The data being processed may be associated with signals with known and/or predictable patterns. A set of key elements are identified for the signal that allow the signal to be reconstructed without saving a complete time series of data for the signal.
Claims15
An implantable cardiac apparatus comprising:
- a memory device;
- a processing device coupled to the memory device;
- a signal receiving circuit coupled to the processing device, the signal receiving circuit to receive a signal from a sensor;
- a key generation circuit coupled to the signal receiving circuit, the key generation circuit configured to evaluate samples of the signal and to store key data representing changes in the signal, wherein the key generation circuit is configured to monitor a plurality of sliding windows for generating slope information associated with the signal, wherein a first one of the sliding windows comprises points preceding a point of interest and a second one of the sliding windows comprises points following the point of interest.
