Therefore, differences in heart rate variability (HRV), an index of autonomic cardiac activity, were examined for right-and left-handed individuals. 120 healthy young university students (75 women, 45 men; M age = 20.4 yr., SD = 1.5) volunteered. Handedness was assessed with the Edinburgh Handedness Inventory and HRV was measured via electrocardiography. The results suggest that the left-handers' HRV was significantly different from that of right-handers on several parameters. The atypical cerebral organization of left-handers may be related to an imbalanced autonomic system that results in higher frequencies of heart irregularities.eninfo:eu-repo/semantics/closedAccessPreference; Longevity; Disease; Risk; Age; Trends; Death; Women; MenArticle10.2466/19.10.PMS.118k24w51183890896250687522-s2.0-84902818974Q3WOS:000338703200016Q4
