1. A wearable device for monitoring vital signs at an extremity, the wearable device comprising:
a housing including an interface surface for pressing against the extremity;
a cuff attached to the housing and having a size and a shape to secure the housing to the extremity and force the interface surface against the extremity when the cuff is worn around the extremity;
a plurality of vital sign sensors disposed in or on the housing and orientated to measure the vital signs from the extremity of a wearer of the wearable device; and
an electrocardiogram (ECG) sensor disposed in or on the housing and coupled to first and second electrodes to measure ECG signals, wherein the second electrode is disposed on the interface surface,
wherein the first electrode is disposed on a second surface of the housing different from the interface surface,
wherein the second surface is opposite the interface surface,
wherein the second electrode is subdivided into a first sub-electrode and a second sub-electrode for common mode rejection of electrical interference while measuring the ECG signals, wherein the first and second sub-electrodes are disposed on the interface surface and electrically insulated from each other.
