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 a disposable extended wear electrode patch; and

    an electronic circuitry comprised within the sealed housing, comprising;

    an externally-powered micro-controller operable to execute under micro programmable control and to write use data comprising ECG data into a memory provided on the disposable extended wear electrode patch, to measure an amount of the use data written into the memory, and to determine an expiration of the disposable extended wear electrode patch once the amount reaches a predetermined threshold;

    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; and

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