摘要：
The frequency range of Electrical Impedance Myography has been extended to 2 MHz, revealing strong increases in reactance starting in the neighbourhood of 3-500 kHz, details depending on muscle and subject. "Reduced variable" Nyquist plots are presented for different segments of the muscle, to demonstrate the unity of the high frequency behaviour with that below 100 kHz. Kramers-Kromg analysis demonstrates compatibility of the rise in X with continued fall in resistance with increasing frequency, and evidence against the "transmission line" hypothesis is presented.
