At a non-uniform depth of the surface layer of the human skin, due to the biophysical necessity of normal functioning of the organism, as well as the presence of pathological processes in certain areas of the body, a temperature correction is proposed. It allows to refine the surface temperature, de...

Peculiarities of programmed through-oesophagus electrocardiostimulation (PTOECS) in 84 coronary patients and 35 healthy have been studied with the purpose of exposure of new additional criterions of lowering of coronary reserve (CR). It was discovered that 22,8% of healthy people and 38,1% patients...

To indentify the predictors of atrial fibrillation (AF) in patients with implanted artificial pacemakers (IPM), 65 such patients were followed up for 6 months. The AF group included 18 (27,7%) patients, while the comparison group consisted of 47 AF-free individuals. AF risk markers included increase...

Restrictive cardiomyopathy (RCMP) is heart disorder with unclear etiology; it can be characterized as disease with disorder of diastolic myocardium function of left ventricle, conditioned by restriction. The chronic heart failure as a syndrome of RCMP can develop as a result of disbalance in system...
