title: [Effect of light negative hydroaeroions on electromagnetic coupling of frog Rana ridibunda auricle].
abstract: It is shown that negative hydroaeroions cause a decrease of the systole strength of freshly prepared auricle and activation of the tired auricle; a decrease of the amplitude and length of the heart trabecula action potentials due to depression of slow input Ca2+ current; shift of the threshold of activation of fast input Na+ current to low potentials; partly elimination of the rise of the auricle systole strength under novodrine. The latter effects were not observed under atropine and indomethacin.
