Abstract
The invention relates to an electrocardiograph sensor mat (100), the mat (100) comprising a multitude of electrodes (104) for acquiring cardiac signals and a plug (200), wherein the electrodes (104) are connected to the plug (200) by electric wires (102), wherein the wires (102) are segmented by switches (202), wherein the switches (202) are switchable between a closed state and an open state, wherein in the closed state the electrodes (104) are electrically connected to the plug (200) and wherein in the open state the electrodes (104) are electrically isolated from the plug (200).

15. An electrocardiograph sensor, comprising:
-
an electrocardiograph sensor mat; a plurality of electrodes coupled to the mat for acquiring cardiac signals from an object to be examined; a plug coupled to the mat, the plug configured to be coupled to an electro-cardiographic mapping (ECM) unit; a plurality of segmented electric wires coupled to the mat, each of the segmented electric wires being arranged between two electrodes of the plurality of electrodes or between an electrode of the plurality of electrodes and the plug; and a plurality of switches corresponding to the plurality of segmented electric wires for selectively connecting the two electrodes or the electrode and the plug between which each segmented electric wire is arranged, respectively, wherein each switch is operable using pressurized gas, wherein supplying and releasing the pressurized gas to and from the switch moves an interrupt contact to selectively close and open an electrical connection across the corresponding segmented electric wire. - View Dependent Claims (16, 17, 18, 19)

20. An electrocardiograph sensor, comprising:
-
an electrocardiograph sensor mat; an electrode on or in the mat for acquiring cardiac signals from an object to be examined when the mat is arranged in contact with the object; a segmented electric wire on or in the mat, and arranged between the electrode and a plug, the plug being configured to output signals from the electrode; a switch connected to the segmented electric wire for selectively connecting the electrode and the plug, wherein the switch is operable using pressurized gas; and at least one tube on or in the mat, the at least one tube being configured to supply the pressurized gas to the switch responsive to a pressure actuator, wherein the switch comprises; a chamber configured to receive the pressurized gas via the at least one tube; and an interrupt contact movable from an open state to a closed state in response to pressure resulting from presence of the pressurized gas in the chamber, wherein the interrupt contact provides an electrical interconnection in the segmented electric wire in the closed state.
