Abstract

A monitor device and associated methodology are disclosed which provide a self contained, relatively small and continuously wearable package for the monitoring of heart related parameters, including ECG. The detection of heart related parameters is predicated on the location of inequipotential signals located within regions of the human body conventionally defined as equivalent for the purpose of detection of heart related electrical activity, such as on single limbs. Amplification, filtering and processing methods and apparatus are described in conjunction with analytical tools for beat detection and display.

Claims

1. A method for monitoring human heart related status parameters, comprising:

locating inequipotential heart related signal locations on the human body within an equivalence region of said body;

placing a sensor having at least two electrodes on said body, said electrodes mounted to engage said signal locations;

detecting a heart related signal indicative of said heart related status parameters from said electrodes; and

processing said signal to extract said heart related parameters from said signal.
