title: [Experimental assessment of the resistance of grounded electrocardiographs to outside line electrically synphasic interference].
abstract: By studying the problem of the electrocardiographs resistance to synphasic interferences it became possible to recommend measuring the noise-stability through the use of an equivalent resistor of synphasic noises and by applying the coefficient of synphasic rejection. Patterns for measurement of these parameters are proposed and several measuring circuit assessed. Principles underlying search for quantitative values for parameters of electric skin resistances used in the circuits are given.
