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

  • a sealed housing having a rounded isosceles trapezoid shape with substantially straight edge on a proximal end that is longer than a substantially straight edge on a distal end and configured to be removably secured into a receptacle on an electrode patch that comprises a battery electrically interfaced to a pair of electrical pads on the receptacle;

    a set of electrical contacts that protrude from a bottom surface of the proximal end of the sealed housing and correspond with further electrical pads on the receptacle;

    a patient feedback button located on the proximal end of the sealed housing on a surface opposite the electrical contacts on the bottom surface; and

    electronic circuitry comprised within the sealed housing, comprising;

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

    a micro-controller electrically interfaced to the electrocardiographic front end circuit and operable to execute under micro-programmable control to sample the electrocardiographic signals sensed by the electrocardiographic front end circuit, to stage each electrocardiographic signal sample in a buffer, to compress each of the staged electrocardiographic signal samples, to further buffer each of the compressed electrocardiographic signal samples, and to write the buffered electrocardiographic signal samples to memory; and

    a flash memory electrically interfaced with the micro-controller and operable to store the buffered samples of the electrocardiographic signals.
