An implantable cardiac device incorporating a processor and a waveform generation circuit incorporating a high voltage capacitor wherein the processor is adapted to charge the capacitor to an initial voltage, less than the peak voltage, and then measure the leakage current occurring across the capacitor at the initial voltage. If the leakage current occurring across the capacitor at the initial voltage is less than a preselected value, selected so that the corresponding leakage current across the capacitor when the capacitor is charged to the peak voltage is within an acceptable tolerance range, the processor then does not perform any further reforming of the capacitor. Alternatively, if the leakage current across the capacitor at the initial voltage is greater than the preselected value, even the processor is adapted to charge the capacitor to a higher voltage, such as the peak voltage, and retain the capacitor at the higher voltage so that the capacitor may be reformed as a result of the application of the higher voltage.
