Rectilinear Biphasic Waveform Characteristics
The following table shows the Rectilinear Biphasic™ waveform’s characteristics when discharged into 25 ohm, 50
ohm, 100 ohm, and 125 ohm loads at a maximum energy setting of 200 Joules.
The efficacy of ZOLL's Rectilinear Biphasic waveform has been clinically verified during a ventricular fibrillation (VF)
and ventricular tachycardia (VT) defibrillation study. This study (which was conducted using ZOLL M Series
defibrillators) and the findings are described below. Since the E Series unit's rectilinear biphasic waveform employs the
same first and second phase timing, the same first and second phase currents/voltages and essentially the same
mechanisms for controlling defibrillation waveshape, the ZOLL M Series and ZOLL E Series defibrillation waveforms
are considered equivalent.
