Cardiovascular effects of several physical and psychological stressors were investigated. Indirect continuous blood pressure as well as heart-rate were recorded. Systolic, diastolic, and mean blood pressure as well as heart-rate were recorded. Different patterns of cardiovascular activation during different stressors were obtained. The Valsalva manoeuvre evoked a basic negative feedback baro-receptor response. Physical exercise (bicycle ergometer stress) evoked an overriding of the baro-reflex sympathetic stimulation to fulfil metabolic needs. Psychological stressors such as a TV-game (‘space invaders’), a binary choice program and mental arithmetic produced a pattern of autonomic nervous stimulation which can be described as extra-metabolic or psychophysiological. Possible differences in reaction patterns between psychological stressors are discussed in the light of a literature study. ‘Active’ and ‘passive’ coping may be of importance.
