Mental Stress Testing Using Classification and Regression Tree
M. V. Voitikova and R. V. Khursa

The Classification and Regression Tree has been used for decision taking process and diagnostics of the hemodynamic response to mental stress testing. Using ambulatory blood pressure monitoring signal, Data Mining algorithm determined the five types of hemodynamic reactions, including hyperactivity, hypertensive and atypical reaction, accompanied by a significant decrease in pulse pressure has been offered. The proposed classification of the hemodynamics can be used to detect abnormalities of hemodynamics and cardiovascular system, as well as increased risk of arterial hypertension.

Key words: Data Mining, Classification and Regression Tree, mental stress testing, '7±2' test, Stroop color test, information test, ambulatory blood pressure monitoring
