PATIENT CARE: Traditional defibrillation uses a monophasic waveform: a single energy pulse. Monophasic electrical current travels in one direction from one electrode or paddle through the heart to the other electrode. In a successful attempt the energy converts the lethal rhythm to a rhythm with a pulse, and to be successful, this type of defibrillation must deliver high energy (200 or more joules).

The biphasic defibrillator delivers current through the heart in two directions, flowing through the heart and back again to the first electrode. Biphasic ...
