Development of methods for monitoring of electrocardiograms, impedance cardiograms and seismocardiograms.

Cardiovascular diseases remain the main cause of morbidity and mortality in Lithuania, and early detection of those diseases is one of opportunities to reduce this problem. Usage of information technologies including clinical decision support systems, telemedicine networks and computer analysis of cardiac signals, can serve this purpose. Therefore, the presented paper deals with development of a system for the analysis of 12-lead electrocardiograms (ECG), impedance cardiograms (ICG) and seismocardiograms (SCG) in the aim to use it in a wider cardiologic teleconsultative system. Such a complex set of signals makes it possible to monitor the electric (ECG), hemodynamic (ICG) and mechanical (SCG) properties of cardiac activity. The hardware for synchronous recording of 12-lead ECG, ICG and SCG as well as the software containing programs for signal input, recognition, measurement, analysis and data transmission has been developed.
