Precision methods and devices for the diagnostics of cardiovascular diseases are the one of the main directions of modern technology development in the field of medical instrument making. However, at this stage of development there are a few overall devices that allow for the diagnostics of cardiac muscle with precise accuracy and without internal interference in the body. This study considers the methods for measurement of biopotentials from the surface of the human body by means of electrocardiographic nanosensors. The device developed in the laboratory No. 63 of the Institute of Non-Destructive Testing of the National Research Tomsk Polytechnic University, its parameters and main characteristics are considered. The article focuses on the use of more sensitive equipment for more detailed study of the human body. The results of measurements carried out by means of the developed device are given.
Simson’s method employed in cardiological diagnostics detects the presence or absence of late ventricular potentials to indicate cardiac pathologies. It has been a long time since the development of Simson’s method, but it is still used in clinics and is often mentioned in studies related to high-resolution ECGs and averaging of ECG signals. An optimal algorithm of high-resolution ECG averaging was chosen and implemented in this study. Efficiency of Simson’s method was assessed on the cardiac signal recorded using a modern hardware and software complex. The result of the study showed no relationship between late ventricular potentials and localized micropotentials on the ST interval in individual cardiac pulses.
Current measuring high-precision methods and devices are one of the most important modern engineering development lines in optimal energy consumption sphere. However, there are a few small-sized instruments which allow conducting precision measurements without breaking the circuit. This paper presents information about conducted Faraday Effect research and general construction of the simple fiber optic current sensor (FOCS). Researched sensor conception is used in prototype which is developing by team of laboratory number 63 of National Research Tomsk Polytechnic University Nondestructive Testing Institute. Required tests and accuracy analysis were conducted. Research results confirm that fiber optic current sensors provide high-precision measurement and proposed methodic is effective.
Precision methods and devices for diagnostics of cardiovascular diseases are one of the main directions for development of modern technology in the field of medical instrument engineering. However, there are no small devices that allow for the diagnostics of cardiac muscle with precision accuracy and without operative intervention at this stage. This study presents the problems associated with cardiovascular diseases (CVD) and the analysis of various organizations engaged in development of efficient means for CVD diagnostics. Two-component FitzHugh - Nagumo model and heart condition imaging algorithm are considered. Aspects of work aimed at designing and developing of the hardware and software complex based on the information obtained with the help of an electrocardiograph on nanosensors. The obtained results are presented.
