ECG

To the Question about the Reciprocal Conformity of the Transition Zone in the Chest Leads ECG, Heart Rate and Cerebral Hemodynamics

This work is devoted to research of features of the vegetative support of activity of young persons, their cerebral hemodynamics depending on the localization of the transition zone in the chest leads ECG in the process of performing active orthostatic test. Registration of ECG, parameters of cardiorhythmography, reoentsefalografii was carried out using the diagnostic complex «Valenta».

The Functional State of Systemic Hemodynamics Russian and Foreign Students at Orthostasis

This work is devoted to the comparative analysis of the functional state of systemic hemodynamics in Russian and foreign students depending on the localization of the transition zone in the chest leads of ECG during the active orthostatic test. Having assessed physical development, we measured the parameters of arterial pressure and ECG using the module «Electrocardiogram» APK «Valenta». The prevalence of asthenic type of physique in foreign students against the deficiency of physical development determines the vertical position of the heart.
