Abstract
A definition of heart-rate variability (h.r.v.) is given. The use of h.r.v. measurement in both clinical applications and the neural cardiovascular research is discussed. For the latter applications, four different signals describing h.r.v. are reviewed. It is shown that these signals are based on modifications of one model, namely the integral pulse frequency modulator. In Part 2, a hardware device for measuring h.r.v. based on one of these modifications is described.
Sommaire
L'article donne une définition de la variabilité du rythme cardiaque (v.r.c.). Il traite de l'application des mesures de v.r.c. aussi bien en clinique que dans la recherche cardio-vasculaire neurale. Dans ce dernier cas, quatre signaux différents mesurant la v.r.c. sont révisés. Ils démontrent que ces signaux se basent sur des modifications d'un modèle, le modulateur intégrateur d'impulsions, en fréquence. Dans la deuxième partie, l'article décrit un matériel servant à mesurer la v.r.c., et qui se base sur l'une de ces modifications.
Zusammenfassung
Eine Definition der Herzfrequenz-Veränderlichkeit (HRV) wird gegeben. Die Verwendung von HRV-Messungen in klinischen Verwendungen und Neural-Kardiovaskulär-Forschung wird erörtert. Für die letzteren Anwendungsgebiete werden vier verschiedene Signale zur Beschreibung von HRV behandelt. Es wird gezeigt, daß diese Signale auf Modifikationen eines Modells beruhen, nämlich dem integralen Impulsfrequenzmodulator. In Teil 2 wird die Hardware zur Messung von HRV auf der Basis einer dieser Modifikationen beschrieben.
