Design of acquisition devices management subsystem for IEEE 1073 compliant software agents.

The paper addresses the issue of device management system design for software agents compliant with IEEE 1073 device communication standard. Based on middleware architecture the device control layer represents a universal versatile object-oriented application-programming interface. The approach presented in the paper allows to implement plug-and-play integration and interoperability of medical acquisition devices within the medical device system be means of common middleware services. Adherence to Medical Data Information Base nomenclature, component part of IEEE 1073 communication standard, adds necessary consistency to presented component-based infrastructure.

[A program package of collection and mathematical processing of ECG data on the basis of COM architecture].

The paper deals with general questions of the Component Object Model (COM) architecture for ECG software applications. Here their common structure is presented, the benefits and constraints of component-based applications are considered. Being a component model, COM allows one to build any application the functionally complete modules. Each module is developed by the particular protocol that gives developers a possibility to provide effective interoperability between such components. The separate part of the article is devoted to reliability and performance issues of the component-based ECG applications. The approach described in this article permits one to solve a number of problems facing medical software developers by using the effective and flexible component architecture. As implementation of the discussed architecture, a software ECG system being developed by a team of authors is presented.

[Specific features of QRS-complex identification algorithms for real-time ECG systems].

The paper reviews the existing methods for identifying QRS complexes. An attempt is made to make a well-defined classification of available algorithms in an approach to QRS detection. Emphasis is laid on the consideration of specific requirements for such algorithms by computer-aided real-time ECG systems. A task of choice of the most suitable method is formulated. An algorithm based on the well-known principles of frequency-time detection is proposed as an alternative solution of this task. The algorithm makes it possible to single out QRS complexes from real-time ECG and to effectively make a digital signal processing by available optimized libraries. The method initially used in the Matlab package has been integrated within the laboratory computerized ECG system.
