How Does a Biphasic Defibrillator Work?
As BiphasicDefibrillator.com explains, the earliest defibrillators were monophasic, which means that they passed an electrical current in just one direction to try to reset the heart. Biphasic defbrillators use an electrical current that flows in two directions to shock the heart. The advantage of using biphasic defibrillators is that less electrical current is needed to successfully shock the heart, which makes these devices more effective to restore the heart’s regular rhythm more quickly.
