1. A system for biometric monitoring comprising:
a patch having a first side adapted to adhere to a patient's skin and an opposing second side;
a plurality of electrodes carried by the patch and adapted to be in electrical communication with the patient's skin, further comprising:
a first electrode, and
a second electrode;
a flexible printed circuit carried by the patch and comprising:
an electrical pad located on a front side,
a trace located on the front side and adapted to provide electrical communication between one of the plurality of electrodes and the electrical pad;
a cradle having a back side proximate to and affixed to the second side of the patch and an opposing front side distal the patch;
wherein the patch comprises:
a first arcuate edge portion having a first endpoint and a second endpoint, wherein the first arcuate edge portion extends around the first electrode along an outer periphery of the patch,
a second arcuate edge portion having a first endpoint and a second endpoint, wherein the second arcuate edge portion extends around the second electrode along an outer periphery of the patch,
a third arcuate edge portion extending from the first endpoint of the first arcuate edge portion to the first endpoint of the second arcuate edge portion along an outer periphery of the patch, and
a fourth arcuate edge portion extending from the second endpoint of the first arcuate edge portion to the second endpoint of the second arcuate edge portion along an outer periphery of the patch;
wherein a first portion of a back side of the flexible printed circuit, which directly opposes the electrical pad is affixed to the front side of the cradle;
wherein a second portion of the flexible printed circuit is positioned between the first side and the second side of the patch with the back side of the flexible printed circuit proximate the cradle and the front side of the flexible printed circuit proximate the plurality of electrodes; and
wherein the electrical pad is adapted to physically contact and electrically engage an electrical contact located on a biometric monitoring device carried by the cradle.

a fourth arcuate edge portion extending from the second endpoint of the first arcuate edge portion to the second endpoint of the second arcuate edge portion along an outer periphery of the patch, wherein the fourth arcuate edge portion further comprises:
a concave edge portion adjoining the second arcuate edge portion, and
a linear top edge extending parallel to a line projected through the center of the first electrode and a center of the fourth electrode;
a first notch in the patch perimeter adjacent the first arcuate edge portion and the third arcuate edge portion,
a second notch in the patch perimeter adjacent the second arcuate edge portion and the third arcuate edge portion,
a third notch in the patch perimeter adjacent the first arcuate edge portion and the linear top edge,
a fourth notch in the patch perimeter adjacent the second arcuate edge portion and the concave edge portion,
a flexible printed circuit extending through the aperture, wherein at least a portion is carried between the first layer and the second layer, comprising:
an electrical pad located on a front side, and
a trace located on the front side and adapted to provide electrical communication between the first electrode and the electrical pad; and
a cradle having a back side proximate to and adhered to the second layer and an opposing front side distal the second layer, wherein a perimeter of the cradle is contained entirely within an area defined by a perimeter of the second layer;
wherein the patch is adapted to carry the first electrode, second electrode, third electrode, and fourth electrode in electrical communication with the patient's skin;
wherein a first portion of a back side of the flexible printed circuit, which directly opposed the electrical pad is affixed to the front side of the cradle;
wherein a second portion of the flexible printed circuit is positioned between the first layer and the second layer of the patch with the back side of the flexible printed circuit proximate the second layer and the and the front side of the flexible printed circuit proximate the first layer; and
wherein the electrical pad is adapted to physically contact and electrically engage an electrical contact located on a biometric monitoring device carried by the cradle; and
