1. A wearable device, comprising: a housing; a modular mount for mounting the housing to a first external body surface, wherein the first external body surface is a wrist location of a first arm of a wearer, wherein the modular mount comprises a band and a frame, wherein the housing is removably seated in the frame, and wherein the band can encircle a wrist of the first arm of the wearer; a first electrical contact disposed on the housing, wherein the first electrical contact contacts skin at the first external body surface when the housing is mounted on the first external body surface; a second electrical contact disposed on an outside surface of the modular mount, wherein the second electrical contact can be contacted by skin of a second external body surface, wherein the second external body surface is a location of a second arm of the wearer; and a signal conditioner disposed in the housing and electrically connected to the first and second electrical contacts, wherein the signal conditioner extracts an electrocardiographic waveform from voltage fluctuations between the first electrical contact and the second electrical contact; wherein the signal conditioner is in electrical contact with the second electrical contact when the housing is seated in the frame, and wherein unseating the housing from the frame removes electrical contact between the signal conditioner and the second electrical contact.
