Preliminary Medical Studies of Electrocardiograph on Nanosensors

Abstract

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.

Methods and Approaches for Automatic Processing and Storage of High-Potential Electrocardiogram Registered by Hardware and Software Complex on Nanosensors

“…A hardware and software complex based on nanosensors capable of recording signals from 0.3 μV with a sampling frequency of 32 kHz and 64 kHz was developed. ECG is currently being studied and analyzed [4,5]. The preclinical studies carried out in healthy volunteers showed the possibility of recording the cardiac micropotentials from 0.3 μV with duration from 0.3 ms and the relationship between the micropotential parameters and the human heart state [6].…”
