    Nyckelord :adrenaline; axillary blockade; beta-receptor blockader; calcium channel blockers; cholinergic blockingagents; felodipine; hypertension-primary; noradrenaline; skeletal muscle; sodium nitroprusside; stress-psychologicai; vascular resistance;

    Sammanfattning : The cardiovascular and sympatho-adrenal responses to a standardized mental stress test (Stroop's colour word conflict test CWT) were studied in 63 healthy and 11 hypertensive men by intraarterial pressure measurements, forearm blood flow by occlusion plethysmography and noradrenaline (NA) and adrenaline (ADR) determinations in arterial and venous plasma. One study included central hemodynamics by right heart catheterization and NA turnover by an isotope dilution method, permitting studies of NA kinetics in the whole body and in a regional vascular bed (the forearm) in hypertensive patients and age-matched controls.
