GENDER-RELATED DIFFERENCES IN NONLINEAR INDICES OF HEART RATE VARIABILITY (2007)
F. Beckers, D. Ramaekers, A. E. Aubert
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...
AUTOMIC CARDIAC CONTROL IN ATHLETES AND NON- ATHLETES AT REST (2007)
A. E. Aubert, F. Beckers, D. Ramaekers
The effect of different types of physical training on heart rate variability was evaluated in 10 aerobic trained athletes, in 7 anaerobic trained athletes, in 7 rugby players (mixed type training)...
THE INFLUENCE OF TRAINING ON HEART RATE VARIABILITY IN HEALTHY OLDER ADULTS. (2007)
B. Seps, F. Beckers, D. Ramaekers, A. E. Aubert
The effect of one-year physical training on heart rate variability in older adults was evaluated in 14 healthy men (age> 55 year). Measures of heart rate variability were obtained in both time and...
Parasympathetic heart rate modulation during parabolic flights (2003)
During parabolic flight short periods of microgravity and hypergravity are created. These changes influence cardiovascular function differently according to posture. During the 29th parabolic flight...
Effects of melanocortins on cardiovascular regulation in rats (2002)
1. Of the melanocortin peptides, gamma(2)-melanocyte-stimulating hormone (MSH) has been attributed a cardiovascular effect, inducing an increase in blood pressure and heart rate. Although still...
Head out of water immersion as simulation study: an heart rate variability study (2002)
During head out of water immersion (HOI), the hydrostatic pressure on the tissues of the lower limbs causes an increase in thoracic blood volume and a high vascular perfusion. This blood shift...
Heart rate variability during gravity transitions (2002)
During parabolic flight short periods of microgravity and hypergravity are created. During standing position time domain analysis showed higher vagal modulation of the autonomic nervous system in...
INTRODUCTION: The correlation dimension (CD) method is related to chaos theory and is used to quantify heart rate variability (HRV). The CD is a measure for the amount of correlations present in the...
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...

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...
Aubert, A E, Jordaens, L, Waleffe, A, De Geest, H, ...
Ninety-three patients, who underwent DC shock ablation were reviewed over a mean follow-up period of 54 months (range 3 to 84 months). These patients (46 male and 47 female, mean age: 58 years) had...
Denef, B, Aubert, A E, De Geest, H
Atrial transport function and the corresponding transmitral flow and stroke volume depend on the timing of atrial contraction. To study the influence of short atrioventricular delay (AVD) on these...
BARACCA, E., LONGHINI, C., AGGIO, S., BRUNAZZI, C., AUBERT, A. E., PANSINI, R.
The present study applies a non-invasive method to the quantitative evaluation of left ventricular stiffness in normal subjects and in patients with ischaemic heart disease (IHD). We have studied 20...
Effect of short atrioventricular delay on cardiac output (1990)
Denef, B, Aubert, A E, De Werf, V, De Geest, H
Short atrioventricular (AV) delay modifies late diastolic filling dynamics. The effect of this change on cardiac output (CO) was studied in closed chest, AV blocked canine preparations (N:10), during...

Orthogonal atrial appendage sensing (1986)
Aubert, A E, Wyman, M G, Denys, B G
The characteristics of electrograms derived from a solid platinum-iridium pacing catheter tip in contact with the right atrial appendage are compared to those derived from a Target-tip electrode....
In the superior vena cava of anaesthetized open chest dogs the axial pressure gradient (delta P) was measured simultaneously with the blood flow velocity (V) under a variety of preload conditions....
Intramyocardial pressure in the canine heart. An experimental study (1985)
During 11 acute open-chest experiments with dogs, intramyocardial pressure was measured in the anterior wall of the left ventricle with a miniature pressure transducer mounted on a 1.6 mm diameter...
The influence of intrathoracic and intraluminal pressure on venous pressure pulse propagation velocity in the superior vena cava was investigated in acute canine experiments. The propagation velocity...
Apparent pulse wave velocity in the canine superior vena cava (1983)
In order to evaluate clinically recorded jugular vein pulses it is necessary to understand the transmission process of the right atrial pressure pulse through the caval veins up to the jugular veins....
