Scatter points in red are the threshold for EMI for the implantable neurostimulator (N5) tested across the seven different waveforms in WTMD simulator. For each waveform, PMEDs were exposed to maximum field generated in WTMD simulator (see Table 1) in order to investigate any potential EMI. Bars represent measured exposure field strengths in actual WTMDs. The “averaged max measured” fields are averaged over the neurostimulator lead loop area
