Abstract
Defibrillator electrode and electrical circuit for generating pulses of energy at the electrodes of a defibrillator comprises an energy storage means, and a switch for supplying energy to the electrodes from the storage means, when the switch is closed. A shunt switch is connected in parallel with the energy storage means, and to a junction on the output side of the supply switch, to form a safety circuit. The shunt switch has a normally closed condition in which it shunts the electrodes, being opened only for the duration of the shock treatment.
