1. A method for establishing a blood pressure model, comprising:
- acquiring pulse wave data, electrocardiographic data, blood pressure data, and body mass indexes of a plurality of subjects to be examined, wherein the blood pressure data comprises systolic blood pressure data and diastolic blood pressure data;
determining pulse wave transit time and pulse wave intensity ratios based on the pulse wave data and the electrocardiographic data;
establishing a systolic blood pressure model indicative of a relationship between systolic blood pressures and the pulse wave transit time and the body mass indexes at least based on the systolic blood pressure data, the pulse wave transit time, and the body mass indexes; and
establishing a diastolic blood pressure model indicative of a relationship between diastolic blood pressures and the pulse wave intensity ratios and the body mass indexes at least based on the diastolic blood pressure data, the pulse wave intensity ratios, and the body mass indexes;
wherein the systolic blood pressure model and the diastolic blood pressure model constitute the blood pressure model.
