Defibrillation waveforms in implantable cardioverter-defibrillators
Defibrillation waveforms in implantable cardioverter-defibrillators
Figure A shows the monophasic, exponentially decaying pulse was the waveform used in the first generation of ICDs. Figure B shows the biphasic waveform, which is generated with a single capacitor by switching the output polarity during discharge. Each division is 2 milliseconds.
