1. An electrode system for sensing heart activity comprising a wristband adapted to be worn on the wrist of one hand and having inner sensing electrode means directly engagable with such wrist;

  • insulating barrier means extending over said inner sensing electrode means for shielding the same against contact with any part of the wearer'"'"'s body except said wrist;

    outer sensing electrode means carried by said wristband and electrically isolated from said inner electrode means by said insulating barrier means;

    said inner and outer sensing electrode means being disposed on oppositely-facing sides of said wristband with said barrier means interposed between said inner and outer sensing electrode means;

    said outer sensing electrode means being exposed and adapted for selective contact by the fingers of the wearer'"'"'s other hand; and

    sensing circuit means disposed in said wristband in electrical circuit with said inner and outer electrode means for sensing electrical signals derived therefrom that are representative of the electrical activity of the wearer'"'"'s heart.
