"Basal" palmar skin potentials and body fluid potassium

"Basal" palmar skin potentials and body fluid potassium

M J Christie. Med Hypotheses. 1976 Sep-Oct.

Abstract

When palmar eccrine sweat glands are inactive the potential difference between palmar skin and a prepared forearm site is a function of the ratio of external (electrode electrolyte) and internal (tissue fluid) potassium concentrations. Evidence indicates that this "basal" palmar skin potential changes systematically with changes in ECF K+, and may be used to monitor such shifts, as, for example, in stress.
