Scientists from Penza State University have developed software for electrocardiogram analysis, which is based on the analysis of the data distribution histogram. This innovative development has already been patented and can be used for early detection of heart disorders in patients, the press service of the Ministry of Education and Science of the Russian Federation reported.
Scientists from Penza State University, which is subordinate to the Ministry of Education and Science of Russia, have improved existing medical devices for diagnosing cardiovascular diseases. It will become possible to detect abnormalities in the heart at earlier stages. <…> The ECG signal is converted into a data distribution histogram using a computer program.
The Ministry of Science and Higher Education of Russia reported that researchers propose to integrate the developed program into existing devices for electrocardiography and Holter monitoring.
This will allow for faster and more accurate analysis of the heart's function. This method could become the basis for a system to support medical decisions, which will reduce the likelihood of error and speed up diagnosis.
In addition, the program will be useful for telemedicine. Thanks to the possibility of using it with fitness trackers, it will help athletes and active lifestyle enthusiasts monitor physical activity.
The developed software converts the electrocardiogram into a histogram showing the distribution of data. One of the key indicators that scientists use to analyze the cardiogram is the probability density distribution.
In the course of laboratory studies conducted at Perm State University, the effectiveness of this scientific development was confirmed. The program revealed characteristic changes in the evaluated parameters in both healthy people and patients with cardiovascular diseases. The shape of the histogram in healthy people and patients with heart problems turned out to be different.
We consider the electrocardiographic signal as a technical signal, the variability of which can be assessed over time. And we evaluate the signal as a whole.
The device can function in real time, when the results are immediately displayed on the device screen or in a special smartphone application, or in stand-alone mode, when data from the electrocardiograph or Holter is transmitted via a wireless network to a cloud server for subsequent analysis. The cardiologist will be able to see preliminary results on the computer screen.
The invention is already protected by a patent, but the developers plan to expand its use. They want to collaborate with scientists from the Medical Institute of PSU to use the program to predict the risk of cardiovascular diseases in patients.
Earlier, the State Corporation "Rosatom" and the Moscow Engineering Physics Institute created a laboratory specializing in bioprinting. This laboratory will develop biocompatible substitutes for blood vessels from patient cells. The key element of the laboratory is a biofabricator.
