Ecg Sampling Rate Controlled by Signal Contents
نویسنده
چکیده
This paper presents the ECG-dedicated algorithm performing the signal sampling at the variable rate. The local value of sampling interval is controlled by the bandwidth function representing the medical data density. The achieved data compression ratio equals 3 and the distortion level is very low. Practical considerations on adaptive antialias filtering and hardware implementation complete the paper.

Low Power Adaptive Analog Front End for ECG Signal Acquisition System
A low power adaptive sampling rate ECG signal acquisition system is proposed. The system uses a capacitive coupled (CC-ECG) sensor which is easily wearable and particularly suited for long term application. An ultra-low power instrumentation amplifier with a superior noise figure followed by a filter bank extracts the desired component from the collected signals. An ultra-low power variable res...
متن کاملEcg Based Heart Rate Monitoring System Implementation Using Fpga for Low Power Devices and Applications
This paper proposes a new design to monitor the Heart Rate from Electrocardiogram (ECG) signal. The proposed design is based on the concept of identifying the voltage level of the R-wave complex component of the ECG signal above a threshold level. A 100 Hertz sample rate is selected to sample the complex ECG signal. A dual-counter based calculation method is used to obtain the mathematical valu...
متن کاملHeart Rate Variability Classification using Support Vector Machine and Genetic Algorithm
Background: Electrocardiogram (ECG) is defined as an electrical signal, which represents cardiac activity. Heart rate variability (HRV) as the variation of interval between two consecutive heartbeats represents the balance between the sympathetic and parasympathetic branches of the autonomic nervous system.Objective: In this study, we aimed to evaluate the efficiency of discrete wavelet transfo...
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...
متن کاملAn ECG Compressed Sensing Method of Low Power Body Area Network
Aimed at low power problem in body area network, an ECG compressed sensing method of low power body area network based on the compressed sensing theory was proposed. Random binary matrices were used as the sensing matrix to measure ECG signals on the sensor nodes. After measured value is transmitted to remote monitoring center, ECG signal sparse representation under the discrete cosine transfor...
