Nonlinear analysis of cardiological signals towards clinical applications
نویسندگان
چکیده
This work is dedicated to the study of cardiac rhythm. It results from a collaboration with the Cardiology and Neurology Departments at Liège University Hospital. The applications considered are essentially twofold: on the one hand, prognosis regarding the health of patients suffering from congestive heart failure, through studying long range correlations and scale invariance in their cardiac rhythm; one the other hand, diagnosis of sleep apnea by means of a dedicated processing of the patient’s cardiac rhythm. Both studies are based on the so-called RR signal, i.e. the sequence of time intervals between successive ventricular contractions.

Prediction of Above-elbow Motions in Amputees, based on Electromyographic(EMG) Signals, Using Nonlinear Autoregressive Exogenous (NARX) Model
Introduction In order to improve the quality of life of amputees, biomechatronic researchers and biomedical engineers have been trying to use a combination of various techniques to provide suitable rehabilitation systems. Diverse biomedical signals, acquired from a specialized organ or cell system, e.g., the nervous system, are the driving force for the whole system. Electromyography(EMG), as a...
متن کاملA Review of Surface-Enhanced Raman Spectroscopy on Potential Clinical Applications Towards Diagnosing Colorectal Cancer
Colorectal cancer (CRC) is one of the leading cancers in the world and early-screening is still the best method of cancer patient survival. However, colonoscopy as the current gold standard is not without flaws and an emerging technique called surface-enhanced Raman spectroscopy (SERS) coupled with machine learning is a possible candidate that could be applied in parallel with colonoscopy. This...

متن کاملEfficiency of Target Location Scenarios in the Multi-Transmitter Multi-Receiver Passive Radar
Multi-transmitter multi-receiver passive radar, which locates target in the surveillance area by the reflected signals of the available opportunistic transmitter from the target, is of interest in many applications. In this paper, we investigate different signal processing scenarios in multi-transmitter multi-receiver passive radar. These scenarios include decentralized processing of reference ...
متن کاملA New Approach to Detect Congestive Heart Failure Using Symbolic Dynamics Analysis of Electrocardiogram Signal
The aim of this study is to show that the measures derived from Electrocardiogram (ECG) signals many a time perform better than the same measures obtained from heart rate (HR) signals. A comparison was made to investigate how far the nonlinear symbolic dynamics approach helps to characterize the nonlinear properties of ECG signals and HR signals, and thereby discriminate between normal and cong...
