Abstract: The aim of this thesis is to obtan basic comperhension about
electrocardiogram analysis and CardioA, computer-aided system for on-line and
off-line analysis of the exercise ECG data. The data model and binary format for
storing signals were closely examined, as well as the functionality oh the
possibility tp access the existing ECG data from remote location through TCP/IP
network. Solution based on client/server principle and three-tier architecture
has been developed. The existiong data model od CardioA system represents data
layer. Middle layer has two modules, one consisting of two parts for the
computer running CardioA system and the other for the client computer. It
includes the communication protocol and the buffering mechanism to accomodate
remote access particularities. The graphical user interface and the basic
functionality of the third layer - client software follows the the existing off-line
analysis system. We have implemented teh system in Java and evaluated its design
with performance analysis.
