Claim 2:
3. The method in accordance with claim 2, wherein the ECG frequency domain parameters are studied and verified to get the analytical validation results, including:
when a range of the ECG PDSs of subjects is within a first frequency range, the ECG frequency domain parameters are affected by HR and HRV at a lower level than a first impact level threshold; the ECG frequency domain parameters are depended on P-QRS-T complexes, which reflect abnormal cardiac condition caused by abnormal cardiac contraction dynamics resulting in changes of the P-QRS-T complexes;
when the range of the ECG PDSs of subjects is within a second frequency range, the ECG frequency domain parameters are affected by HR and HRV at a higher level than a second impact level threshold; the ECG frequency domain parameters reflect the interactive effects of the HR, HRV and P-QRS-T complexes and changes of the ECG frequency domain parameters over different ECG signal lengths are below a predetermined degree of change threshold.
