Early detection and monitoring of heart diseases increase human quality of life and this can prevent negative consequences. It is even more important because it can prevent sudden deaths. In today's technology, these operations can be done with telemedicine systems. In this work, appropriate methods have been proposed for telemedicine systems. The proposed system is of two classes and is based on...
This paper present a wearable platform, for cardiac signal monitoring, developed by using conductive threads into a cloth article. For reading the human body, impedance variations were used flexible electrodes developed for the wearable ECG platform. The dry ECG electrodes have been developed by knitting technology. The electrodes have been integrated into the textile assembly together with the electronics...
Noninvasive fetal electrocardiogram (NI-FECG) monitoring is important instrument for detection of fetal distress. Despite the technology advancements of the signal processing techniques achieved in recent years, the accuracy of NIFECG monitors is not satisfactory till now and this technology still practically unexploited in the clinical practice. But because of the great prospects of this method the...
In this paper, we propose a fully ear-worn long-term blood pressure (BP) and heart rate (HR) monitor to achieve a higher wearability.

A simple heart rate (HR) monitoring system designed and developed using the Giant Magneto-Resistance (GMR) sensor is presented in this paper. The GMR sensor is placed on the wrist of the human and it provides the magneto-plethysmographic signal. This signal is processed by the simple analog and digital instrumentation stages to render the heart rate indication. A prototype of the system has been built...
QRS detection plays a key role in processing, measurements and analysis of ECG signals. There is a recognized need for reliable and objective evaluation of their performances. This task becomes difficult taking into account multiple data source, different data storage formats as well as various execution environments and modes. The aim of this project was to develop an automatic, configurable and...
Accurate estimation of heart rates from electrocardiogram (ECG) signals during intense physical activity is a very challenging problem. In this study we investigated a novel technique to accurately reconstruct motion-corrupted ECG signals and HR based on time-varying spectral analysis. The algorithm is called Spectral filter algorithm for electrocardiogram Motion Artifacts and heart rate reconstruction...
A Premature Ventricular Contraction (PVC) is an irregular heartbeat caused by the spontaneous firing of the Purkinje fibers when the Sinoatrial node fails to establish the normal pacing of the heart. PVCs can impair cardiac function and lead to greater risk of cardiovascular disease. PVCs are usually monitored with a Holter monitor or event monitor, which are bulky and can be uncomfortable for the...

Electrocardiography (ECG) can be used to monitor patients for myocardial ischemia, which is a precursor to myocardial infarction. Ambulatory ECG is often contaminated with motion artifact. In this paper, we investigate the effect of motion artifact on myocardial ischemia alarms and on estimates of the ECG signal quality. The presence of motion artifact in an ambulatory ECG leads to false identification...
