Abstract
A defibrillator, or alternatively, paddles therefor adapted with the wave-forming inductance of the discharge circuit disposed between the two paddles of the discharge circuit of the defibrillator and is so disposed in the paddles as to couple in a cancelling manner when the paddles are placed face-to-face. In a preferred embodiment, the waveform inductance is split substantially equally in each of the two paddles wherein each of the inductors have a value of substantially half the total necessary inductance for the forming of the waveform for the defibrillating wave. The respective coils of the inductors are wound in reverse directions, one with respect to the other so that the total inductance generated in a discharge directly through the paddles is substantially nil.
