• a backing comprising an elongated strip with a midsection connecting two rounded ends, wherein the midsection tapers in from each of the rounded ends and is narrower than each of the two rounded ends;
• a pair of electrodes, each electrode positioned on one of the rounded ends of the backing on a contact surface to capture electrocardiographic signals;
• a flex circuit coupled to each of the electrodes;
• a non-conductive receptacle affixed to the backing and operable to removably receive an electrocardiography monitor, the non-conductive receptacle comprising:
• electrical contacts, wherein the electrical contacts are provided on a surface opposite the backing;
• a compartment;
• and
• a battery disposed within the compartment;
• a processor powered by the battery to write the electrocardiographic signals into memory;
• and
