1. An electrocardiogram (ECG) apparatus comprising:
an input configured to receive a biometric cardiogram signal of a patient;
a compensation signal combiner for selectively producing a compensated biometric cardiogram signal of the biometric cardiogram signal of the patient; and
processor circuitry configured to receive the compensated biometric cardiogram signal and to produce an ECG reflective of the compensated biometric cardiogram signal and to output a signal corresponding to high frequency response of the compensated biometric cardiogram signal to the compensation signal combiner to compensate for low response of the biometric cardiogram signal of the patient to high frequency spikes whereby an ECG is produced by the processor circuitry having pacing signal contribution within the biometric cardiogram signal cancelled.
