Claim:
1. An extended wear electrocardiography patch, comprising: a flexible backing formed of an elongated strip of stretchable material with a narrow longitudinal midsection evenly tapering inward from both ends, the elongated strip adherable only on a contact surface defined on each of the ends, and operable to serve as a crimp relief to facilitate compression of the narrow longitudinal midsection in response to compressional and torsional forces; a pair of electrocardiographic electrodes respectively affixed to and conductively exposed on the contact surface of each end of the elongated strip; a flexible circuit affixed on each end to the elongated strip and comprising a pair of circuit traces each originating within one of the ends of the elongated strip, respectively; and electrically coupled to one of the electrocardiographic electrodes, respectively; a non-conductive receptacle securely adhered on one end of the elongated strip opposite the contact surface and operable to removably receive an electrocardiography monitor, the non-conductive receptacle comprising electrode terminals aligned to electrically interface the pair of the circuit traces to the electrocardiography monitor; a laterally-extendable strain relief defined in the flexible circuit underneath such that the non-conductive receptacle on the flexible backing covers the strain relief, wherein the strain relief is operable to facilitate extension and rotation of the flexible circuit in response to tensile and torsional forces; and a pair of strain relief cutouts comprised in the strain relief that each face towards the other strain relief cutout and is positioned transverse to a length of the flexible backing, each strain relief cutout partially extending transversely from and continuing longitudinally to a side of the flexible circuit different than the other strain relief cutout, one of the pair of the circuit traces following a path formed on the flexible circuit between the pair of the strain relief cutout.
