Abstract: A heart activity measurement device for an individual including: a processing unit; at least one measurement cable, including a first end suited for connection to the processing unit in order to form an input for an electrical potential, and a second end; a support, ready for an individual to wear, where the support supports the cable so as to keep a predefined path for the cable relative to the skin of the individual when the support is worn. The cable is laid out such that when the support is worn, any contact between an electrically conducting part of the cable and the skin of the individual is prevented. The second end of the cable does not have any electrode for contact with the skin. The support is further laid out for keeping a predefined spacing between a measurement portion of the cable and the skin of the individual.
