1. An extended wear electrocardiography and physiological sensor monitor recorder, comprising:

  • a sealed housing adapted to be removably secured into a non-conductive receptacle on a disposable extended wear electrode patch that comprises a battery electrically interfaced to a pair of electrical pads on the non-conductive receptacle and comprising a cavity on a bottom surface to accommodate the battery on the electrode patch and a set of electrical contacts that protrude from the bottom surface adjacent to the cavity that correspond with further electrical pads on the non-conductive receptacle; and

    an electronic circuitry comprised within the sealed housing, comprising;

    an externally-powered micro-controller operable to execute under micro programmable control through firmware that is stored in a program memory unit of the micro-controller;

    an electrocardiographic front end circuit electrically interfaced to the micro-controller and operable to sense electrocardiographic signals through electrocardiographic electrodes provided on the disposable extended wear electrode patch, each of the electrocardiographic electrodes adapted to be positioned axially along the midline of the sternum for capturing action potential propagation; and

    an externally-powered flash memory electrically interfaced with the micro-controller and operable to store samples of the electrocardiographic signals.
