Table 2. Subject impedance measurements at low currents with ECT electrodes.
Table includes Thymatron (pre, post and average measurements) measurements, impedance analyzer measurements at 1 kHz, and the lumped circuit values approximating impedance spectrum (>100 Hz data only) with the 1 kHz impedance of that circuit. EIS curve fit element parameters are for Trial 1. Note, impedance analyzer Trial 1 is for 1 V (10–1000Hz), Trial 2 is 1 V (1–1000Hz), and 100 mV (10–1000 Hz). IMP: Impedance.
