1. A method for analyzing high-frequency QRS waveform data, comprising:
acquiring the high-frequency QRS waveform data corresponding to exercise electrocardiogram (ECG) data; wherein the exercise ECG data comprises ECG data of each of a resting stage, an exercise stage and a recovery stage;
selecting the high-frequency QRS waveform data in a first time period as first reference waveform data; wherein the first time period consists of a period during the resting stage before the exercise stage and a period during the exercise stage, or the period during the exercise stage;
determining a first reference point according to a point with a minimum root-mean-square voltage in the first reference waveform data, and determining a second reference point in the first reference waveform data, wherein a time of the second reference point is earlier than that of the first reference point in the first reference waveform data and the second reference point has a maximum root-mean-square voltage within a portion of the first reference waveform data prior to the first reference point;
determining a first amplitude drop relative value according to respective root-mean-square voltages of the first reference point and the second reference point;
acquiring a target voltage from the high-frequency QRS waveform data and determining a maximum voltage corresponding to the high-frequency QRS waveform data based on the target voltage;
selecting, from the high-frequency QRS waveform data in a second time period, a point with a maximum root-mean-square voltage as a third reference point and a point with a minimum root-mean-square voltage and time later than the third reference point as a fourth reference point; wherein the second time period comprises a period having a starting point with a time equal to or earlier than that of a starting point of the first time period and an ending point later than an ending point of the first time period;
determining a voltage difference according to respective root-mean-square voltages of the third reference point and the fourth reference point;
screening the high-frequency QRS waveform data with the first amplitude drop relative value greater than or equal to a first preset threshold; and
determining vascular response capability according to a ratio of the voltage difference corresponding to the screened high-frequency QRS waveform data to the maximum voltage.
