Gender-related Differences in Nonlinear Indices of Heart Rate Variability
The effect of day-night variations was evaluated in both a female and a male population of healthy subjects. A total of 239 subjects were included in this study, of which 119 male and 120 female. 24 hour Holter recordings were used to analyze heart rate variability. Power spectral indices (total power, low and high frequency power) were calculated together with the nonlinear indices fractal dim...
متن کاملUnderestimation of cardiac vagal control in regular exercisers by 24-hour heart rate variability recordings.
OBJECTIVE To examine whether ceiling effects at long inter beat intervals (IBIs)cause an underestimation of cardiac vagal control in regular exercisers by time and frequency-domain measures of respiratory sinus arrhythmia (RSA). METHODS 24-hour ECG and respiration recordings were performed in 26 regularly exercising subjects, actively engaged in aerobic training for the past year, and enrolle...
متن کاملChanges in heart rate and heart rate variability as a function of age in Thoroughbred horses
We investigated changes in heart rate (HR) and HR variability as a function of age in newborn foals to old Thoroughbred horses. Experiments were performed on a total of 83 healthy and clinically normal Thoroughbred horses. Resting HR decreased with age from birth. The relationship between age and HR fit the equation Y=48.2X-0.129(R2=0.705); the relationship between age and HR for horses 0-7 yea...
متن کاملReduced 24 hour ambulatory blood pressure and abnormal heart rate variability in patients with dysorexia nervosa.
D ysorexia nervosa (DN) includes two types of eating disorder: anorexia nervosa (AN) and bulimia nervosa (BN). AN is a syndrome characterised by changes in eating habits, distortions of body shape, and a refusal to maintain even minimally normal body weight. BN is a syndrome encompassing repeated episodes of binge eating, followed by inappropriate compensatory behaviours such as self induced vo...
متن کاملHeart rate variability and arrhythmic patterns of 24-hour Holter electrocardiography among Nigerians with cardiovascular diseases
BACKGROUND Facilities for Holter electrocardiography (ECG) monitoring in many Nigerian hospitals are limited. There are few published works in Nigeria on the use of 24-hour Holter ECG in cardiac arrhythmic evaluation of patients with cardiovascular diseases. OBJECTIVE To study the clinical indications, arrhythmic pattern, and heart rate variability (HRV) among subjects referred for 24-hour Ho...
