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.

2. An apparatus to determine physiological status of an individual, comprising:
-
a. a wearable sensor device adapted to be worn in an equivalence region of said individual'"'"'s body; b. at least two electrodes attached to said wearable sensor device, said electrodes adapted to be mounted within said equivalence region and to detect a heart-related signal; c. a pressure sensor within the wearable sensor device adapted to detect a pressure-related signal and to be in contact with a portion of said individual'"'"'s body that is in proximity to said at least two electrodes; d. a processor in electronic communication with said at least two electrodes and the pressure sensor programmed to determine a pulse transit time from said heart-related signal and said pressure-related signal. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
