Smaller 85-μF capacitors lower DFT energy in porcine VF; hypothesis-generating for human ICD capacitor optimization.
Does a smaller capacitance value (85 microF) reduce the defibrillation energy requirement compared to a larger capacitance value (140 microF) in a porcine model of ventricular fibrillation?
Smaller capacitance values (85 microF) result in lower energy requirements for biphasic waveform defibrillation compared to larger capacitance values (140 microF) in a porcine model.
