Fig. (1) “While we found two triphasic waveforms were significantly worse than a monophonic waveform, we found no statistically significant evidence that any triphasic waveforms was superior to the biphasic control waveforms”Y-axis in volts, X-axis in milliseconds – 16 ms in total**Significantly less efficacious than monophasic (p<0.05)† More efficacious than biphasic (p<0.01)
