A low impedance high capacitance double layer capacitor (also known as a "super cap") is used to supply energy to charge a high voltage capacitor. Upon a command from a controller and/or an operator, the high voltage capacitor administers a shock to a patient in order to treat ventricular fibrillation. If a power source is used to augment the double layer capacitor in supplying energy to the high voltage capacitor, the power source charges the capacitor during a dwell time, which is a time between shocks or at start up. Once the decision is made to administer a shock, the high voltage capacitor is charged by the high voltage capacitor and the power source. By adjusting the energy stored in the high voltage capacitor through a voltage limiting device such as a switch mode converter current source, the draw on the power source can be reduced while allowing for a reduced dwell time without affecting the performance of the defibrillator. The use of a double layer capacitor can be used to supply energy to charge a high voltage capacitor without the power supply, and is useful in external and internal defibrillators, and can be used in leadless paddles to allow the operator the greatest freedom of movement.
