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
Fully Automatic AED Plus’s Rectilinear Biphasic Waveform employs the same first and second phase
timing, similar first and second phase currents/voltages and essentially the same mechanisms for
controlling defibrillation waveshape, the M Series
®
and Fully Automatic AED Plus defibrillation
waveforms are considered substantially equivalent.
