Abstract
A method for analyzing a high frequency (HF) electrogram signal including (a) providing at least one electrogram signal from an electrode located within a subject's body, (b) measuring the electrogram signal at a high frequency during a specific segment of a cardiac cycle, generating a HF electrogram signal, and (c) having a computer measure at least one time-varying parameter of the HF electrogram signal. Related apparatus and methods are also described.
Claims20
IPG (implantable pulse generator) apparatus for analyzing a high frequency (HF) electrogram signal comprising:
- an electrode for use inside a living body;
- a signal pickup configured to pick up an electrogram signal comprising a high frequency (HF) component;
- a measurement unit for measuring a high frequency (HF) component from the electrogram signal only during less than 40% of a cardiac cycle;
- and
- an analyzer for analyzing the HF component of the electrogram signal,
- wherein:
- the signal pickup, the measurement unit and the analyzer are comprised within an implantable container;
- and
- the analyzer is configured to measure at least one time-varying parameter of the HF electrogram signal.
