Patients with arrhythmias would greatly benefit from daily ECG monitoring, both for diagnosis and therapy optimization. The aim of this study was to simulate several ECG monitoring strategies which could help in optimizing a home monitoring device. Simulations were performed using data from patients implanted with DDD-CLS pacemaker for Brady-Tachy Syndrome (Burden II Study). The data analysis was...
Physical Activity Monitoring is a device that can measure the human activity quantity quantitatively through Heart Rate detection in real time. R-Spike detection of ECG is required for this Heart Rate detection. Since Physical Activity Monitoring System is usually used during activity or exercise, however, signal measured in ECG System is contaminated by diverse noises. Diverse noises become the factors...
A wireless ECG monitoring system is presented that is able to perform high-quality ECG signal acquisition, beat detection, and real time monitoring of skin-electrode impedance which can be used to monitor the presence of motion artefacts. The whole system consumes only 170μW while performing local beat detection. The beat detection algorithm was verified against the MIT-BIH arrhythmia database and...
Nowadays, Heart related diseases are on the rise. Cardiac arrest is quoted as the major contributor to sudden and unexpected death rate in the modern stress filled lifestyle around the globe. A system that warns the person about the onset of the disease earlier automatically will be a boon to the society. This is achievable by deploying advances in wireless technology to the existing patient monitoring...
A new flexible, dry electrode is examined for recording surface electromyographic signals and compared to a conventional Ag/AgCl electrode. A suitable dry electrode would enable practical implementation of wearable mobility monitoring systems. Results from a preliminary experiment are presented in this paper. Measurements were performed on the right tibialis anterior during a series of small and large...
This paper presents the design of a complete portable package for a low cost embedded programmable ECG measurement and monitoring system implemented by a fast algorithm in detecting ECG characteristics points. This proposed system is expected to monitor the electrical activity of heart of the patient under critical care more conveniently and accurately for diagnosing which can be interfaced with computer...
The design issues of a low-cost microcontroller-based device for monitoring the cardiac activity are presented. Two channels are configured for the acquisition of an electrocardiogram and a phonocardiogram, using a PIC16F877 microcontroller connected to a DMF5005 graphic LCD module to display the waveforms. The analog circuitry is simply illustrated, while main digital hardware and software modules...
The aim of this paper is to discuss the design and evaluation process of software for the analysis of ECG signal in a Holter system. The software was developed with RAD Studio 2009 using the Object Pascal language. The complete design and programming process was oriented to obtain different classes that encapsulate the needed functionality and combine them to obtain the final application. The analysis...
The final generation of ProeTEX prototypes has been delivered in April 2010: it is based on two sets of sensorized garments devoted to monitor the health status of emergency operators working in harsh environments. This new release of garments shows several improvements with respect to the previous ones, and it is characterized by a major specialization to the requirements imposed by the different...
We have developed a non-invasive system for monitoring cardiac vibrations, respiration and body movement of in-bed hospitalized patients and elderly people who need constant care. These physiological parameters are recorded by an infrared emitting diode and a photo transistor, which are attached between spring coils in bed mattress. The infrared emitting diode diffuses infrared light into the mattress...
The aim of this paper is to demonstrate a highly integrated architecture for direct Analog-to-QRS detection for ultra low power single chip implementation suitable for long term wearable monitoring. A novel variable input-feature correlated asynchronous sampling technique is proposed for direct sampling-cum-data compression at the ECG electrodes with embedded mixed-signal algorithm for direct recognition...
In the present work we apply a fully automatic procedure to the analysis of signal coming from a sensorized T-shit, worn during the night, for sleep evaluation. The goodness and reliability of the signals recorded trough the T-shirt was previously tested, while the employed algorithms for feature extraction and sleep classification were previously developed on standard ECG recordings and the obtained...
Paroxysmal atrial fibrillation (PAF) is a difficult disorder to investigate because of its intermittent and sometimes asymptomatic nature. The aim of this study was to simulate several daily ECG monitoring strategies applied on data extracted from Burden II Study (patients implanted with pacemaker for Brady-Tachy Syndrome). Daily monitoring strategies were obtained by varying the following key parameters:...
This paper presents low-power radio-frequency identification (RFID) technology for intelligent healthcare systems. With attention to power-efficient communication in the body sensor network, RF power transfer was estimated and the required low-power ICs, which are important in the development of a healthcare system with miniaturization and system integration, are discussed based on the RFID platform...
When a patient returns home from a hospital, a doctor might still want to monitor the heart condition remotely. An ECG sensor based on wireless sensor network technology can provide this information, but the energy consumption of this solution should be considered. This paper describes the energy trade-off between ECG signal transmissions and on-node feature extraction based on QRS complex detection.
The aim of the research presented in this paper was to test and evaluate the possibility of T-wave alternans (TWA) detection with the use of standard ambulatory ECG monitors. In development work there is proposal of author's advanced method allowing to remove from signal any distortion and disturbances making impossible further analysis.
Cardiovascular Disease (CVD) is one of the leading causes of death which underlie one third of the world's death. The online monitoring and early warning message to cardiovascular system might protect sudden heart disease and save human's life. Scientists have used various vital signs to detect and predict CVD, such as blood pressure (BP), electrocardiogram (ECG), sphygmogram (SPG) and pulse wave...
In this paper, an unconstrained and noninvasive system to detect heart rate (HR), respiratory rate and extract pulse arrival time (PAT) during sleep is proposed. The system consists of PPG sensor module embedded in a pillow and CC-ECG (capacitor coupled-ECG) sensor module. From the PPG sensor, we acquired heart rate and respiratory rate during sleep with simple peak detection algorithm. Besides, by...
The central monitoring system is made up of four parts. Those are nerve ache RF (radio frequency) treatment modules, physiological signal detecting modules, a communication server, and a central monitoring computer. It can not only treat nerve ache by using RF pulse, but also monitor the ECG, heart sound, temperature and impedance. Both the design circuits of nerve ache RF treatment module and detecting...
This study investigates the rate estimation problem encountered in rehabilitation exercise monitoring by using noninvasive portable sensors. The purpose of this paper has two main parts.
