Association of Type D personality with the autonomic and hemodynamic response to the cold pressor test

摘要: Mechanisms relating Type D personality to poor health are largely unknown, with autonomic nervous system function being a candidate. This study examined the physiologic response cold stress. Undergraduates (N = 101, 84% female) underwent pressor test. An electrocardiogram, impedance cardiogram, and blood pressure were recorded. was assessed by self-report questionnaire. associated increased systolic diastolic reactivity. Exploratory analyses showed men respond respiratory sinus arrhythmia (i.e., higher parasympathetic activity), decreased pre-ejection period larger sympathetic while women reciprocal pattern. In conclusion, an exaggerated hemodynamic stress, which may contribute risk of hypertension in individuals.
