ABSTRACT:
A cardiac stimulation device and method monitor and store discrepancies in sensor indicated rates determined from two or more sensors generating signals related to metabolic demand. One feature included in the present invention is a sensor cross-check record that stores the time, duration and sensor indicated rates whenever individual sensor indicated rates differ by more than a discrepancy threshold. This record allows a clinician to monitor an abnormal patient condition or determine if a sensor is not functioning properly or is programmed sub-optimally. Another feature provided by the present invention is a sensor cross-check histogram in which sensor indicated rate differences are stored. Histogram data aids the clinician in selecting programmable operating parameters that control the calculation of sensor indicated rates and the rate response of the cardiac stimulation device.
