Biphasic defibrillators deliver currents in two directions. In one direction, the current moves from one defibrillator paddle to the other. Then, the current reverses. Although the exact reason is unknown, this multiple direction current lowers the threshold for successful defibrillation, saving more lives.

ya i feel its good to have biphasic than monophasic,because it cause less myocardial damage and less skin burn.

Almost, all AEDs (Automated External Defibrillators) use a monophasic waveforms that send an electical wavefrorm through the heart in one direction. Biphasic AEDs send a shock through the heart in one direction and again in the reverse direction. Biphasic AEDs use less energy than monophasic AEDs – hence they can be smaller.

A monophasic requires more energy (volts) because the shock only travels though the heart once. A Biphasic defibrillator requires less energy because the shock goes through the heart and then bounces back to shock again (it’s is kind of like an echo).
