Various methods and systems are provided for a fabric cover including a plurality of integrated electrodes for measuring an electrocardiogram signal of a patient in direct contact with at least a subset of the plurality of integrate electrodes. As one example, a fabric cover for an infant incubator or warmer includes a plurality of electrodes spaced apart from one another within a measurement area of a surface of the fabric cover adapted to have direct contact with a patient, the plurality of electrodes including a topmost electrode extending across an entire width of the measurement area, a bottommost electrode extending across the entire width of the measurement area, and a set of electrodes arranged between the topmost electrode and bottommost electrode, in a direction perpendicular to the width, within the measurement area.
