In this paper a simple and viable on-line method to transmit ECG under hardware restricted environments is derived and its performance illustrated in simulation studies. The proposed scheme makes use of an ECG signal lossless compression technique for the communications channel optimization. Obtaining a better compression rate guarantees both the sending costs and the memory resources reduction. Simulation...
This paper presents a novel and efficient algorithm of ECG compression in real time monitoring systems, updated with each new input signal sample. This algorithm tries to improve the compression ratio of the captured signal by means of an optimal noise threshold in terms of hardware complexity and memory requirements. Threshold estimation is computed, using the instantaneous standard deviation, in...
A real- time, denoise, and compress algorithm based on the wavelet transform (WT) for abdominal electrocardiograms (AECG) signals is designed. In this study an algorithm is designed which achieves an AECG with minimal noise and high compression rate (66.7%) while keeping the AECG quality at a clinically acceptable level. This is done at the first stage before extracting the fetal electrocardiogram...
This paper presents a Medicine/Engineering multidisciplinary research project, in which a European Telecardiology system has been developed for the continuing monitoring of patients using GPRS/GSM. The system consists in a portable terminal and a call center that provide 24h-duty medical supervision and assistance. The system includes advanced signal processing for the recognition of cardiac pathologies...
