Many of these difficulties can be solved by the development of adequate research paradigms together with the application of psychophysiological register techniques. Various studies show the influence that negative affect emotions like fear and anxiety have in human health. Heart affections are one of the most often health problems derived from an intense and continuous emotional activation. In order to know in detail the sympathetic mechanisms of influence on cardiovascular activity, we propose an experimental design of cardiac defense response (RCD) together with register of the pre-ejection period (PEP) obtained by impedance cardiography and electrocardiogram. The RCD is a well established paradigm of cardiovascular reactivity elicited by the unexpected display of an intense and short auditory stimulus (500 ms, 105 dB). The PEP measures the latency between the onset of electromechanical systole and the onset of left ventricle ejection, being a reliable index of beta-adrenergic activity on left ventricle. |
