[Exercise ECG test as a method for non-invasive detection of myocardial ischemia].
OBJECTIVE
To improve the exercise ECG analysis for non-invasively detection of myocardial ischemia.


METHODS
The newly developed measuring system of exercise ECG defines ST segment area and STA/HR slope as the new characteristic parameters, thus can sensitively detect myocardial ischemia. Some methods were proposed to reduce noise and artifacts for effective sampling of exercise ECG.


RESULTS
14 exercise ECG records were sampled and analyzed in clinical exercise test. It was found that the new parameters are very effective and sensitive to myocardial ischemia. The results show that the method is reliable and stable.


CONCLUSIONS
The method improves one of the evaluating indexes of exercise ECG analysis. It is quite promising for clinical application in future.
