Editorial Heart rate / ST slope RAPHAEL
In 1979 Berenyi et al first proposed that the rate of change of ST segment with respect to heart rate (the HR/ST slope) might be an indicator of the amount of prejudiced myocardium as judged by the coronary arteriogram.' This suggestion has been extensively studied particularly by the Department of Cardiovascular Studies at The University of Leeds. In 1982 these workers reported an excellent co...
متن کاملAnalysis of Slope Based Heart Rate Asymmetry using Poincaré Plots
Heart rate asymmetry (HRA) is considered as a physiological phenomenon seen in heart rates of healthy subjects. In this article, we propose a novel heart rate asymmetry index and assess the discriminative power of proposed index in comparison with conventional heart rate asymmetry indices. As an illustrative example we discriminate patients suffering from congestive heart failure (CHF) from a h...
متن کاملLead specificity of the maximum ST/heart rate slope response.
Sir, Once more correspondence columns have borne witness to the confusion caused by the Leeds exercise test. Yet again Professor Linden and his colleagues have been able to claim that their protocol has not been adhered to-and of course on this occasion they are correct in that respect.'2 They have, however, chosen to ignore other studies that have followed their protocol meticulously and that ...
متن کاملSLOPE PROFILE MORPHOMETRY AS AN INDICATOR FOR SLOPE MOVEMENT
Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...
متن کاملSlope Filtrations
Many slope filtrations occur in algebraic geometry, asymptotic analysis, ramification theory, p-adic theories, geometry of numbers... These functorial filtrations, which are indexed by rational (or sometimes real) numbers, have a lot of common properties. We propose a unified abstract treatment of slope filtrations, and survey how new ties between different domains have been woven by dint of de...
