[Diurnal pattern of cardiovascular parameters in round-the-clock production operators].
Electric network dispatchers, with high psychoemotional stress level at work, demonstrated inverted diurnal pattern of intershift changes in most cardiovascular parameters. This pattern was smoothed in first shifts with relatively low intensity. Second successive 12-hour shifts could have the pattern smoothed oppositely--if increased work intensity--that proves depleted cardiovascular adaptive resources. Increased intensity of working shift brings about higher intershift changes in prevailing parasympathetic cardiovascular regulation mostly due to daily shift load.
