Developed prototype of network based clinical decision support system consists of database of clinical data and web-based applications for signal and image analysis methods and algorithms. The methods for eye fundus image analysis and ECG P-wave morphology evaluation are the first methods covering two clinical specialties - cardiology and ophthalmology in the system. Network based database and combined...
The topical subject is intensive extraction of information from cardiac signals and using it in diagnostics and assessment status of heart function. The aim of this study is presentation of the analytical method designed for analysis of dynamic interrelations between different cardiac signals - electrocardiogram, impedance cardiogram and seism-cardiogram.
The new method for assessment of interpersonal and inter parameter concatenation during monitoring of vital signals has been developed. Assessment of inter parameter concatenation permitted to reveal some new features of heart functionality when ECG monitoring was performed during various situations. Proposed method and values of concatenation between various processes could serve as indicators of...
The wireless vital signals monitoring system has been developed. It aids to monitor patients with cardiovascular diseases (CVD) and sportsmen. The system consists of wireless electrocardiogram (ECG) and motion signals recording and transmitting device to personal computer and software for signal analysis and evaluation of human functional state. The feedback and warning means has been developed. The...
Physical load is very important and necessary for human organism and for its systems functionality. During bicycle ergometry work we can evaluate the functionality of the human organism. We looked for the complexity measure, which could integrally and simple evaluate organism reaction to physical load. We used ECG RR interval allometric relation and RR interval information dimension. We indicated,...
The basic idea of this work was to develop user- friendly mobile wireless ECG and motion activity recording device, software for real time signal analysis and warning system based on ordinary or pocket PC and designed for home care patients with cardiac risk. The mobile patient device includes 3 channel ECG front-end recorder, 3-axis accelerometer and Bluetooth module. Feedback signaling to patient...
The long JTC interval of ECG can cause the life threatening arrhythmic events and is a non-questionable factor of sudden death. According to some authors, the JT interval gets shorter during 4-6 hours after percutaneous transluminal coronary angioplasty (PTCA) in acute myocardial infarction (AMI). The aim of this study was to determine the influence of early reperfusion on the course of JT interval...
If we want correctly specify human physiological state, it is very important to evaluate the changes of main systems participating in different functions. In this work we are analyzing parameters that characterize these systems, their functional relations, counting information dimension and searching for differences in various investigated groups of persons (sportsmen, healthy persons, patients with...
The aim of this paper is to present a new electrocardiosignals (ECGs) and motion signals telemonitoring and analysis system for sportsmen paddling a canoe or kayak. The developed system is intended to facilitate the couch in optimizing and individualizing the training of elite athletes. The hardware system consists of rower and coach components. Rower components include 5 sensors for monitoring of...
