1. A wearable cardiac signal monitoring device, comprising:
a first removable component configured to monitor and create a record of a cardiac rhythm signal, the first removable component including electronic components comprising a processor, a first printed circuit board, a physical event trigger, and a light-emitting diode (LED), contained within a first rigid housing, wherein the first removable component is configured to be connected, physically and electrically, to other device components, wherein the first removable component is configured to be removed from the wearable cardiac signal monitoring device and sent for data processing after a particular time period for cardiac rhythm signal monitoring is over, wherein the physical event trigger comprises a button and is configured to permit a patient to physically interact with the physical event trigger to mark the record when a patient perceives a cardiac event, wherein the physical event trigger is mechanically supported by a portion of the first removable component, and wherein a portion of the first removable component is substantially rigid to prevent deflections of the electronic components and the introduction of noise or artifacts into the recorded cardiac rhythm signal;
a second rigid housing that contains a second printed circuit board and a battery;
a flexible body comprising multiple layers, including a flexible polymer layer, wherein the flexible body includes a flexible electrode trace, borders of the flexible body have rounded edges, the flexible body is joined to the second rigid housing, and the flexible body is configured to flex at an area where it is joined to the second rigid housing, such that a portion of the second rigid housing may lift away from the flexible body, wherein at least one layer of the flexible body extends beyond at least one other layer of the flexible body creating an edge to the flexible body that is thinner than an inner portion of the flexible body; and
two electrodes disposed on a bottom surface of the wearable cardiac signal monitoring device, wherein the centers of the two electrodes are separated by at least 8.5 cm, and wherein the first rigid housing and the second rigid housing protects the components contained within them, and are made of a water resistant polymer.
