Abstract
A defibrillator applies a defibrillation waveform to a patient. Waveform selection circuitry in the defibrillator uses a reference waveform to give the defibrillation waveform a desired shape. Preferably, a user selects between a plurality of stored waveforms, and the reference waveform is generated from the stored waveform selected by the user. As an alternative to selecting a stored waveform, the user may also create a new waveform, which is then stored for a future selection.
