This paper presents the evaluation of mental stress assessment using heart rate variability. The activity of the autonomic nervous system (ANS) is studied by means of frequency analysis of the Electrocardiogram (ECG) signal. Spectral decomposition of the Heart Rate Variability before smoking and after smoking was obtained. Mental stress is accompanied by dynamic changes in ANS activity. ECG sig...

This paper presents the design, implementation and results related to the storage system of medical information associated to the ECG (Electrocardiography) signal. The system includes the signal acquisition modules, the preprocessing and signal processing, followed by a module of transmission and reception of the signal, along with the storage and web display system of the medical platform. The...

Physikalisch-Technische Bundesanstalt (PTB) database is electrocardiograms (ECGs) set from healthy volunteers and patients with different heart diseases. PTB is provided for research and teaching purposes by National Metrology Institute of Germany. The analysis method of complex QRS in ECG signals for diagnosis of heart disease is extremely important. In this article, a method on Shannon energy...

The main focus of this paper is to design an advanced Electrocardiogram (ECG) signal monitoring and analysis design. Heart is an important part of the human body. Heart diseases are the important factor which cause of death in the world. An electrocardiogram is a device which graphically records the electrical activity of the heart. It is used to identify normal and abnormal heartbeats. Noise f...

Abstract: Electrocardiogram (ECG), a noninvasive technique is used as a primary diagnostic tool for cardiovascular diseases. A cleaned ECG signal provides necessary information about the electrophysiology of the heart diseases and ischemic changes that may occur. It provides valuable information about the functional aspects of the heart and cardiovascular system. The objective of paper is to au...

Medical applications increasingly require complex calculations with constraints of accelerated processing time. These are therefore oriented towards the integration high-performance embedded architectures. In this context, detection cardiac abnormalities is a task that remains high priority in emergency medicine. ECG analysis requires significant computing time since large amount information mu...

Heart is an important part of the human body. Heart diseases are the important factor which cause of death in the world. An electrocardiogram is a device which graphically records the electrical activity of the heart. It is used to identify normal and abnormal heartbeats. Noise filtering is the next step of the QRS detection. In filtering of signal, we have used one band stop filter and a low p...

This paper presents the design related to the electronic system design of the respiratory signal, including phases for processing, followed by the transmission and reception of this signal and finally display. The processing of this signal is added to the ECG and temperature sign, put up last year. Under this scheme is proposed that in future also be conditioned blood pressure signal under the ...
