Evaluation of a none compressed 12-lead ECG transmission via internet using IPSec.

Electrocardiogram (ECG) transmission in real time could involve some problems with the quality of services and security. This paper aims to evaluate a none compressed 12-lead ECG transmission using the Secure Internet Protocol (IPSec), compared with the popular Internet Protocol (IP). Using an analytical model, the transmission performance is estimated in terms of end-to-end delay and loss rate. Our results show that ECG transmission could be assured both security and quality of services.

ECG compression by modelling the instantaneous module/phase of its DCT.

Recent developments in compression methods on the non-linear and non-stationary data, such as electrocardiograms (ECG), have received large attention by the time-frequency analysts. The technique presented in this paper is based on parametrical modeling the instantaneous module as well as the instantaneous phase, estimated directly from the Discrete Cosine Transform (DCT) of each ECG beat. The estimated parameters are then used to reconstruct each recorded beat. In order to evaluate the performance of our technique, data recorded from the MIT-BIH arrhythmia database are used.

An input-delay neural-network-based approach for piecewise ECG signal compression.

We propose an input delay neural network (IDNN) based time series prediction algorithm for compressing electrocardiogram (ECG) signals. Our algorithm has been tested and successfully compared vis-à-vis other popular techniques for its compression efficiency and reconstruction capability.
