[Determination of phases of stress in clinical cardiology]
Abstract:
Aim of the study was to determine criteria of phases of stress reaction in humans to psychoemotional loading taking into account regulatory systems of adaptational reserves of organism. We examined representatives of professions potentially exposed to stress and investigated a spectrum of derangements of regulatory systems of the organism (neurovegetative system and cognitive function) under conditions of development of different phases of stress reaction to psychoemotinal loads. The proposed approach will allow to obtain efficiently quantitative assessment of phases of stress reaction in humans at different levels of adaptation to it. This approach can be used in clinical medicine.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Psychoneuroimmunology: Cardiovascular Disease
