In the beginning phases of EKG technology, patients were necessary to place their hands and feet into sodium chloride baths, a semiconducting method for the faint electric impulses found in the heart. Later, electrical wires were old to transmit heart signals to the machine; eventually the electrodes we use now replaced these wires.
