Hypothesis-generating for redox modulation of K+ currents; requires validation in native cardiomyocytes before physiological relevance is established.
Hydrogen peroxide specifically and reversibly inhibits the fast inactivation of certain voltage-gated K+ channels, supporting its potential role as a metabolic modulator of excitability.
Miera et al. (1992) studied this question.
