A 'typical' HVPC set of parameters are illustrated in Figure 2 below. In this case the pulse duration is set at 200Âµs, the interpulse interval is set at 9800Âµs and therefore 1 cycle will take 10000Âµs to deliver (which is 10ms-milliseconds). If 1 cycle takes 10ms to deliver, the stimulation frequency will be 100Hz.t is argued (see figure 3 below, from www.nervestudy.com) that although the pulses are high voltage (typically 150-500V), they are of very short duration (microsec) and thus the actual (averaged) current flow through the tissues will be low-in the microcurrent range (microamps).
