  • Apparatus for measuring electrical activity in the heart with graphical display of electrode contact with tissue
    Patent number: 5469857
    Abstract: An apparatus for measuring electrical activity in the heart, such as an ECG apparatus, has an input amplifier with multiple inputs to which the respective poles of electrodes introduced into a patient are intended to be connected. The input amplifier includes a sensing stage for sensing the impedance across the amplifier inputs after connection of the electrodes, in order to identify the poles which are in contact with the patient's heart. A display is connected to the input amplifier to graphically indicate which electrode poles are connected, and which are in contact with the heart.
