In this paper proposals on construction of the contactless ECG scanning system hardware are described. The philosophy of the system is based on the idea of creating a simple-to-be-worn dress that includes capacitive ECG sensors the outputs of which are transferred to the A/D converter of a processing device. Contemporary technologies enable sewing of the sensors as well as the connecting wires ...

The purpose of the Evaluating ECG capturing using sound-card of PC/Laptop is provided portable and low cost ECG monitoring system using laptop and mobile phones. There is no need to interface microcontroller or any other device to transmit ECG data. This research is based on hardware design, implementation, signal capturing and Evaluation of an ECG processing and analyzing system which attend t...

BACKGROUND Time-domain analysis of the P-wave in signal-averaged ECG (SA-ECG) recorded from chest leads is an accepted method for evaluating the inhomogeneity of atrial excitation, predictive for atrial arrhythmias. The aim of the study was to determine the value of the SA-ECG technique for intraatrial signal processing. Additional aims were to evaluate the correlation between SA-ECG parameters...

Electrocardiogram (ECG) is considered as the main signal that can be used to diagnose different kinds of diseases related human heart. During recording process, it usually contaminated with noise which includes power-line interference, baseline wandering and muscle contraction. In order clean ECG signal, several removal techniques have been such adaptive filters, empirical mode decomposition, H...

removal of artifacts from bio-signals is a necessary step before automatic processing and obtaining clinical information. recently, many applications of empirical mode decomposition (emd) on biomedical researches have been presented that artifact reduction from bio-signals is one of them. emd separates a time series into finite numbers of its individual oscillations, which are called intrinsic ...

An electrocardiogram (ECG) quantifies the electrical activity of heart to screen for different diseases, although it can be impacted by noise. ECG signal filtering is a crucial pre-processing step that reduces noise and emphasizes characteristic waves in data. In real-world applications, contaminated types Separating desired from noises produced artifacts such as muscle noise, power line interf...

The aim of the present study was to compare heart rate variability (HRV) at rest and during exercise using a temporal series obtained with the Polar S810i monitor and a signal from a LYNX(R) signal conditioner (BIO EMG 1000 model) with a channel configured for the acquisition of ECG signals. Fifteen healthy subjects aged 20.9 +/- 1.4 years were analyzed. The subjects remained at rest for 20 min...

BACKGROUND Telehealth care is a global trend affecting clinical practice around the world. To mitigate the workload of health professionals and provide ubiquitous health care, a comprehensive surveillance system with value-added services based on information technologies must be established. OBJECTIVE We conducted this study to describe our proposed telesurveillance system designed for monito...
