Pulmonary vascular resistance and compliance relationship in pulmonary hypertension

Autor: Edmund M.T. Lau, Philippe Hervé, Denis Chemla, Yves Papelier, Pierre Attal

Publikováno v: European Respiratory Journal. 46:1178-1189

Right ventricular adaptation to the increased pulmonary arterial load is a key determinant of outcomes in pulmonary hypertension (PH). Pulmonary vascular resistance (PVR) and total arterial compliance (C) quantify resistive and elastic properties of

Estimating Right Ventricular Stroke Work and the Pulsatile Work Fraction in Pulmonary Hypertension

Autor: Nicolas Creuze, Denis Chemla, Gérald Simonneau, Florence Parent, Susana Hoette, Vincent Castelain, Marc Humbert, Philippe Hervé, Kaixian Zhu, Yves Papelier

Publikováno v: Chest. 143:1343-1350

The mean pulmonary artery pressure (mPAP) replaces mean systolic ejection pressure (msePAP) in the classic formula of right ventricular stroke work (RVSW) = (mPAP - RAP) × stroke volume, where RAP is mean right atrial pressure. Only the steady work

International audience; This study proposes a Semi-Classical Signal Analysis (SCSA) method for stroke volume (SV) variations assessment from arterial blood pressure measurements. One of the SCSA parameters, the first systolic invariant (INVS1), has b

Background: Baroreflex allows to reduce sudden rises or falls of arterial pressure through parallel RR interval fluctuations induced by autonomic nervous system. During spontaneous breathing, the application of positive endexpiratory pressure (PEEP)

Mathematical modelling of the cardiovascular system and skeletal muscle interaction during exercise

Autor: Yves Papelier, Carlo D'Angelo

Publikováno v: ESAIM: Proceedings. 14:72-88

In this work we present a mathematical model for the coupling of cardiovascular system and metabolism under sport efforts. Effects such as oxygenation, heart rates, flow rates, blood pressure and mass transfer to tissues will be considered. A special

Effect of Exercise Intensity and Repetition on Heart Rate Variability During Training in Elite Trotting Horse

Autor: Claire Médigue, E. Petit, Véronique Billat, Philippe Lopes, Yves Papelier, François Cottin

Publikováno v: International Journal of Sports Medicine. 26:859-867

RR intervals of ten elite trotting horses were recorded during an interval training session performed on track. This study examined two hypotheses. Firstly, like in humans, the hyperpnea combined with a decrease in cardiac autonomic control on heart

Heart Rate Variability during Exercise Performed below and above Ventilatory Threshold

Publikováno v: Medicine & Science in Sports & Exercise. 36:594-600

To examine whether differences in heart rate variability (HRV) can distinguish sub- from supra-ventilatory-threshold exercise and whether the exercise duration at supra-threshold intensity alters cardiorespiratory synchronization.Beat-to-beat RR inte

Noninvasive assessment of cardiac parasympathetic function: postexercise heart rate recovery or heart rate variability?

Autor: Said Ahmaidi, Paul B. Laursen, Martin Buchheit, Yves Papelier

Publikováno v: American Journal of Physiology-Heart and Circulatory Physiology. 293:H8-H10

postexercise heart rate (HR) recovery (HRR) and HR variability (HRV) are commonly used in noninvasive assessment procedures for the determination of cardiovascular parasympathetic function ([3][1], [8][2], [9][3], [15][4], [20][5]). Evaluation of car

Relationship between ventilatory thresholds and systolic blood pressure variability

International Journal of Sports Medicine, 2010, 31 (9), pp.604-609. ⟨10.1055/s-0030-1255064⟩

International audience; During exercise, an increase in respiratory rate amplifies the blood pressure oscillations. This phenomenon is usually intensified when exercise rate exceeds the ventilatory thresholds (VTs). The present study examined whether
