The Effect of Elicited Emotion on Heart Rate Variability (HRV), Evaluating the Mediator Role of Risk Factors

The purpose of this study was to investigate the effect of elicited emotion on heart rate variability (HRV). In this study which was an semi-experimental research, 92 subjects whose age range was 20-40 years participated voluntarily and they were put purposefully in experimental group. The research tools included Procomp HRV Biofeedback, excitement emerging movies and Risk Factors Check list .To analysis the data, Multi and univariate analysis of variance (Repeated measure) were assigned. According to results of the study, between analyses was revealed that the changes between high risk and low risk group was not significant. Due to the obtained results, CAD risk factors cannot be significantly affective for HRV abnormalities prediction in low age group and the need to investigate risk factors on older group is essential
