1. An extended wear electrocardiography and physiological sensor monitor recorder with self-authenticating electrocardiography monitoring circuit, comprising:

  • a sealed housing adapted to be removably secured into a non-conductive receptacle on an electrode patch; and

    electronic circuitry comprised within the sealed housing, comprising;

    an electrocardiographic front end circuit operable to sense electrocardiographic signals through electrocardiographic electrodes provided on the electrode patch;

    flash memory to record the electrocardiographic signals; and

    a micro-controller to periodically write data into a memory of the electrode patch on which the sealed housing is removably secured via the non-conductive receptacle during continuous recording of the electrocardiographic signals via the electrocardiographic front end circuit, to determine an expiration of the electrode patch based on an amount of the data stored in the memory of the electrode patch, and to turn off the micro-controller upon the expiration of the electrode patch.
