Abstract
A flexible multiple electrode assembly includes at least one fixed electrode; at least one extendible electrode; and electrically conductive interconnections coupling the at least one fixed electrode and the at least one extendible electrode to a common connector. The at least one extendible electrode is adapted to be physically separable from the at least one fixed electrode while remaining electrically coupled to the common connector. In one embodiment, an array of fixed and extendible electrodes is configured for the acquisition of electrical pulses from a heart for transmission to an electrocardiograph (EKG or ECG) device.
