ECG on stroop test taken on 250 Hz (sampling frequency) You can use in order to obtain (and compare) the stress (from HRV)

Normal ECG test taken on 250 Hz (sampling frequency) You can use in order to obtain (and compare) the stress (from HRV) (compare with ecg stroop & ecg matematica )

基于eprime程序的经典实验代码，用于srtoop实验。(Eprime program based on the classic experimental code for srtoop experiment.)
