to develop an artificial neural networks-based diagnostic model for coronary heart disease using traditional and genetic factors of CHD (Coronary heart disease). In summary, this study was used to create CHD diagnostic models with the appropriate analytical characteristics. These characteristics consisted of using MLP artificial neural networks. The best accuracy was provided in models that had both genetic and non-genetic factors associated with CHD. The models that had less than a 90% accuracy could potentially serve as a basis for development of software tools for diagnosis and predictors for CHD. The effect of ECG Voltage Changes on Variations of Intrathoracic Amount of Blood Oleg Atkov participated in a study titled The Variations of Intrathoracic Amount of Blood as a Reason of ECG Voltage Changes. Marina Saltykova Ph.D.1, Andre Capderou M.D., Ph.D.2, Oleg Atkov M.D.1, Victor Gusakov M.S.3, Gennagiy Konovalov M.S.3, Leonid Voronin M.D.3, Rustem Kaspranskiy M.D.3, Valeriy Morgun M.D.3, Olivier Bailliart M.D., Ph.D.4, Milan Cermack M.D.5 and Pierre Vaïda M.D.6 were the members of this team. “The main goal of the study was to estimate the influence of the variations of thoracic electroconduction, and heart volume on QRS voltage in humans due to gravity change.” The balance between changes of degree of short circuiting by changes in the amount of blood in thorax and the changes of distance between heart and electrodes as a result of position, form, and volume of the heart are what influence the steadiness. Atkov's inventions After Atkov's time in space, he dedicated most of his work towards the Russian railways and cardiology. Within the cardiology field, Atkov has been a part of 15 major projects that has helped advance the types of technology in cardiology research. He also holds several patents for inventions he produced or helped develop. One of his major inventions was a device for positioning a cardiograph sensor. This invention had seven other cardiology specialist involved. The main objective was to create something that could hold and maneuver an Echocardiograph and an Electrocardiograph at the same time while not being in the way of physicians. This device has paved the way towards greater and more advanced technology for better ultrasound techniques. Another notable invention was the Photogrammetrical plotting projector apparatus for radial nadir point triangulation. This invention was to make sure that a Photogrammetrical plotting projector could take what images it needs at the correct angles and explore new angles that images
