ABSTRACT:
Having prospectively ascertained a patient's transthoracic resistance upon application of a low amplitude exploration current via the defibrillator electrodes, the capacitor of the defibrillator is charged sufficiently for delivery of a minimal peak current, e.g., 25 amps, preselected by the operator as appropriate for attaining defibrillation, and the capacitor is discharged to effect the defibrillation.
