Electode catheter for transvenous defibrillation.
Development of an implantable automatic defibrillator is dependent on achieving a reduction in the energy required for defibrillation, which is related to an optimal electrode configuration. This study investigated the use of a transvenous catheter electrode utilizing the damped sinusoidal waveform; compared the defibrillation effectiveness of varying the configuration of the four electrode units and of using a catheter/subcutaneous metal plate combination; and determined the lowest energy level necessary for near consistent transvenous defibrillation.
