ABSTRACT:
The present invention is directed to a method and apparatus for enhancing high resolution ECG signals acquired with electrodes on the surface of a patient's thorax so that ventricular late potentials can be detected and observed. The ECG signals are detected, measured and digitized and are then processed to remove low frequency components and preferably, common mode signals. Enhancement is then accomplished by filtering out the remaining electrical interference caused by underlying muscle tissue, nerve tissue and environmental noise with a particular adaptive filtering technique.
