In these days, computing environment turns to web environment and a lot of hospitals build information system. A medical services through the web provide patients and doctors with convenience and help experts to communicate with each other. Initially, web provided static text information, but nowadays needs of interactivity between client and server is increasing. In order to diagnose heart diseases, we use 12 channel ECG, stress ECG, holter ECG, etc. These data are a lot of correlation with each other but there are little system managed them with integration. To enhance management efficiency and share medical information, it is necessary to develop integrated ECG management system based the web. In this paper, we use common object request broker architecture(CQRBA) to implement the system. The CORBA is to apply object oriented concept to web. We can implement application easily and reduce costs to maintain and repay because server objects and client objects exist independently. We developed a System to integrate these data using network and to raise management efficiency. we focus on the performance of object web and the implementation of ECG management system based on the web.
