US 2019/0159692 A1 · FAST RECOVERY OF ECG SIGNAL METHOD AND APPARATUS

Abstract

Fast recovery electrocardiogram (ECG) signal method and apparatus are provided. In one embodiment, an ECG apparatus includes an input for receiving a biometric cardiogram signal, such as a Wilson Central Terminal (WCT) signal, and a combiner, such as an adder, for producing a compensated signal. An analog to digital converter provides a digitized version of the compensated signal to a processor. The processor produces an ECG reflective of the compensated signal and also outputs a digital signal corresponding to high frequency response of the digitized compensated signal to a digital to analog converter. The digital to analog converter provides an analog version of the digital signal corresponding to high frequency response of the digitized compensated signal to compensate for low response of the biometric cardiogram signal to high frequency spikes. A resultant ECG is produced by the processor having pacing signal contribution within the biometric cardiogram signal cancelled.

An electrocardiogram (ECG) apparatus comprising:

an input for receiving 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;
an analog to digital converter for providing a digitized version of the compensated biometric cardiogram signal to a digital processor;
the digital processor configured to produce an ECG reflective of the compensated biometric cardiogram signal and to output a digital signal corresponding to high frequency response of the digitized compensated biometric cardiogram signal to a digital to analog converter;
and
the digital to analog converter configured to provide an analog version of the digital signal corresponding to high frequency response of the digitized 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 digital processor having pacing signal contribution within the biometric cardiogram signal cancelled.
