Abstract
A system for testing the attachment of an electrocardiograph (ECG) electrode intended to be used in connection with an electrode monitoring the function of the heart, muscles or other organs to indicate detachment of the electrode from its fixing base, said electrode being provided with voltage monitoring apparatus. The electrode comprises a capacitive sheath insulated from the electrode and from its fixing base and an alternating voltage source arranged to supply a signal voltage to the sheath so that on detachment of the electrode from its fixing base immediately an alternating voltage is induced from the sheath to the electrode.
