[The use of the orthostatic test in practical medical flight expertise in civil aviation]
Abstract:
Comparison of results from HDT administered with different techniques showed that 5-10 min in vertical position are enough to adequately evaluate mechanisms of circulation control. By that time hemodynamic shifts get stabilized. More precise assessment of the circulation regulation can be made when HDT is administered from initial supine rather than sitting position. Analysis of the ECG dynamics allows to elicit latent myocardial injuries. The exact quantitative characteristic of orthostatic disturbances makes it possible to give their pathophysiological estimate.

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
Application of Linearization and Approximation
