title: [Unit for measuring the interference stability of information element selectors for electrocardiac signals].
abstract: The device provides automatic measuring noise immunity of selectors for informative ECG elements. Errors in signal detecting by a reference selector are mainly responsible for a measurement error of noise immunity. The expression to derive a relative instrumental error has been deduced.
