The different states mentioned refer to the four states of resting state, deep breathing state, Valsalva movement and standing movement. The ECG and pulse wave data in different states are recorded, and the recording time of each state is 2 minutes. The resting state means that the tester sits quietly for 2 minutes and maintains normal breathing; the deep breathing state is a breathing cycle with 5 seconds of inhalation and 5 seconds of exhalation, which is repeated 12 times; the Valsalva movement is a deep inhalation, Hold your breath for 15 seconds, exhale vigorously and relax for 15 seconds as an action cycle, repeat four times...
