Electric potential mapping and electrode attachment device comprises: a main cylinder a center piece having a center piece passage for receiving a catheter with its electrode running from a center piece inlet to a center piece outlet a cylinder cap for closing main cylinder a second cylinder which fits inside of and is allowed to rotate relative to main cylinder and at least two electromechanical connections used to connect the device to at least two connectors on an electrode lead, where the device facilitates rotation and movement of each connector relative to the other while retaining continuous electrical connection with heart tissue or other body cavity tissue. The device offers continuous recording of electrical potentials of a body cavity during full rotation of collars, connectors, or connections on a laparoscopic device during HIS bundle mapping, pacemaker electrode anchoring, post anchoring, pacemaker programming, and afterwards.
