title: [Changes in the systemic and intracardiac hemodynamics of healthy persons as affected by emotional tension].
abstract: Twenty-four normal subjects were examined during exposure to emotional stress, simulated by mental arithmetic exercise under time shortage and interfering light and sound stimuli. Hemodynamic parameters were determined on the basis of echocardiographic M-records in resting condition and under mental stress. Irrespective of the baseline hemodynamic type, emotional stress produced a hyperkinetic circulatory response. Increased cardiac index resulted from higher heart rate in the presence of unchanged venous return and stroke index. Myocardial contractility increased to a greater extent in individuals with hypokinetic and eukinetic hemodynamics.
