ABSTRACT:
An implantable cardiac pacer having pacer circuitry for producing output stimulation pulses on leads connectable to a patient's heart includes internal measurement circuitry for producing uncorrected measurement values relative to battery conditions and to pulses from the pacing circuitry. The pacer has a data processing unit with a microprocessor and a RAM device for storing, in dedicated locations, programmed gain and offset correction factors for the uncorrected measurement values. Telemetry means is responsive to the microprocessor for transmitting the uncorrected measurement values and the correction factors to an external programmer/receiver unit. The programmer/receiver unit includes telemetry means for receiving the uncorrected measurement values and the correction factors from the pacer. The programmer/receiver unit further includes a data processing device having an ROM device for storing an algorithm and a microprocessor for calculating corrected measurement values from the uncorrected measurement values and the correction factors.
