Increased total heart rate variability and enhanced cardiac vagal autonomic activity in healthy humans with sinus bradycardia.
Sinus bradycardia can be defined as a sinus rhythm with a resting heart rate of 60 beats per minute or less. While it is assumed that increased autonomic parasympathetic activity is associated with sinus bradycardia, such an association has yet to be proven. The aims of this study were to compute a number of heart rate variability (HRV) parameters in healthy individuals with sinus bradycardia a...
متن کاملIntegrated Central-Autonomic Multifractal Complexity in the Heart Rate Variability of Healthy Humans
PURPOSE OF STUDY The aim of this study was to characterize the central-autonomic interaction underlying the multifractality in heart rate variability (HRV) of healthy humans. MATERIALS AND METHODS Eleven young healthy subjects participated in two separate ~40 min experimental sessions, one in supine (SUP) and one in, head-up-tilt (HUT), upright (UPR) body positions. Surface scalp electroencep...
متن کاملHeart rate variability and heart rate in healthy volunteers. Is the female autonomic nervous system cardioprotective?
AIMS Heart rate variability has been proposed as an indicator of cardiovascular health. Since women have a lower cardiovascular risk, we hypothesized that there are gender differences in autonomic modulation. METHODS AND RESULTS In 276 healthy subjects (135 women, 141 men) between 18 and 71 years of age, 24 h heart rate and heart rate variability were determined. All heart rate variability pa...
متن کاملDiscrimination between Healthy and Sick Cardiac Autonomic Nervous System by Detrended Heart Rate Variability Analysis
Multiresolution Wavelet Transform and Detrended Fluctuation Analysis have been recently proven as excellent methods in the analysis of Heart Rate Variability, and in distinguishing between healthy subjects and patients with various dysfunctions of the cardiac nervous system. We argue that it is possible to obtain a distinction between healthy subjects/patients of at least similar quality by, fi...
متن کاملSinus bradycardia with cardiac asystole.
A case of sinus bradycardia with cardiac asystole was described in this journal (Pearson, 1945). The subsequent history and the post-mortem findings are now recorded. The patient was a woman aged 52 years who had been under observation since February 1943. Her pulse rate varied between 16 and 30 and her main symptoms were attacks of unconsciousness, resembling Stokes-Adams attacks; these were s...
