Why the study?
Does left-handedness correlate with differences in heart rate variability in healthy young adults?
Does left-handedness correlate with differences in heart rate variability in healthy young adults?
Left-handed healthy young adults demonstrate significantly different heart rate variability compared to right-handers, suggesting potential differences in autonomic cardiac activity.
Left-handedness may associate with autonomic differences; hypothesis-generating for HRV research, should not change practice.
Previous studies reported reduced longevity in left-handers with the suggestion that it may be associated with different heart diseases. 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.
