Assignee: MEDTRONIC, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 25:
26. The method of claim 14, comprising:
generating the physiological signal by generating an acceleration signal from at least one axis of an accelerometer having a plurality of axes;
detecting cardiac events from the physiological signal;
delivering the electrical stimulation pulses by generating a pacing pulse in response to a cardiac event detected from the physiological signal; and
determining the first current drain by:
determining a sensor operation current drain by determining an accumulated time of selectively powering each axis of the plurality of axes of the accelerometer for generating the physiological signal;
determining a processing burden current drain required for detecting the cardiac events from the physiological signal; and
determining a therapy delivery current drain by:
determining a pacing impedance;
determining at least one pacing pulse control parameter;
determining a pacing frequency; and
determining the therapy delivery current drain based on the pacing impedance, the at least one pacing pulse control parameter and the pacing frequency; and

determining the first current drain based on at least the sensor operation current drain, the processing burden current drain and the therapy delivery current drain.
