[Temporal evolution of blood pressure and heart rate reaction to various stressors in coronary and non-coronary subjects (author's transl)].
The temporal evolution of systolic and diastolic blood pressure and heart rate in reaction to several stresses is measured in a group of 21 post myocardial infarction and 21 non coronary subjects. Heart rate modifications depend essentially upon the nature of stress: catheterization induces tachycardia while a stressing film induces bradycardia. These observations can be connected to environmental intake or rejection. During catheterization stress, the systolic blood pressure is high in both groups but returns to its normal values as soon as the intervention ends. In response to anxiety films, it persists higher in coronary patients than in normal subjects, who do not seem to react to this kind of stress. These results arise the question of either a longer recuperation, or a different reactivity to symbolic stressors (films).
