1. An improved implantable defibrillator system for producing a truncated capacitor-discharge biphasic-waveform output defibrillation pulse, the implantable defibrillator system being a self-contained human implantable device including a pulse-generating capacitor means for storing an electrical charge, means for internally charging the pulse-generating capacitor means, and means for selectively discharging the electrical charge in the pulse-generating capacitor means through electrodes implanted in a human patient in response to a means for sensing of a myocardial fibrillation in the human patient, the improvement comprising:

  • the pulse-generating capacitor means having an equivalent capacitance value of less than 120 microfarads.
