A wearable electrocardiography monitoring ensemble is provided, which includes a garment made of a compressible and elastomeric material. The garment is wearable about an upper region of the torso and further includes an internal structure forming a compressive bias circumferential to the torso. The ensemble also includes an electrode assembly provided on an inside surface of the garment on an underside of the internal structure. The electrode assembly has a pair of electrocardiography electrodes, a pair of terminated electrical connections that are each coupled to one of the electrocardiography electrodes, and a backing to which the electrocardiography electrodes are affixed. The wearable monitoring ensemble creates a more natural experience for wearers and can be used to produce an expanded dataset for diagnosis because the ensemble can collect data during activities of daily living and can capture cardiovascular events outside of clinical observation, which is otherwise not practicable, especially for athletes.
