The ST-segment depression/heart rate (ST HR) analysis has been found to improve the
diagnostic accuracy of the exercise ECG test in detecting myocardial ischemia. Recently,
three different continuous diagnostic variables based on the ST HR analysis have been
introduced; the ST HR slope, the ST HR index and the ST HR hysteresis. The latter utilises
both the exercise and recovery phases of the exercise ECG test, whereas the two former are
based on the exercise phase only. This present article presents a computer program which …
The ST-segment depression/heart rate (ST HR ) analysis has been found to improve the diagnostic accuracy of the exercise ECG test in detecting myocardial ischemia. Recently, three different continuous diagnostic variables based on the ST HR analysis have been introduced; the ST HR slope, the ST HR index and the ST HR hysteresis. The latter utilises both the exercise and recovery phases of the exercise ECG test, whereas the two former are based on the exercise phase only. This present article presents a computer program which not only calculates the above three diagnostic variables but also plots the full diagrams of ST-segment depression against heart rate during both exercise and recovery phases for each ECG lead from given ST HR data. The program can be used in the exercise ECG diagnosis of daily clinical practice provided that the ST HR data from the ECG measurement system can be linked to the program. At present, the main purpose of the program is to provide clinical and medical researchers with a practical tool for comprehensive clinical evaluation and development of the ST HR analysis.
