Abstract
An electrode for use with an external defibrillator for a patient includes a first combination circuit including a circuit node electrically coupled to an adapter for coupling to the defibrillator. The circuit node is further coupled to a monitoring node defined by a monitoring segment of a first pad of the electrode and to a therapy node defined by a therapy segment of the first pad of the electrode. The therapy segment is electrically insulated from the monitoring segment. The first combination circuit further includes a capacitor coupled between the circuit node and the therapy node. The electrode of this disclosure hence provides additional solutions for reducing ECG artifact during the operation of the electrode.
