Abstract
The present invention relates to method and apparatus for heart-level blood pressure estimation based on ensemble learning. The invention relates to the technical field of biomedical technology. The method comprises: acquiring radial arterial blood pressure related information and a hydrostatic pressure of the radial artery of a subject; performing blood pressure conversion based on the radial arterial blood pressure related information and the hydrostatic pressure of the radial artery to obtain at least two brachial arterial blood pressure values; inputting the at least two brachial arterial blood pressure values into a trained correction model to obtain a target brachial arterial blood pressure value. The present invention realizes the conversion from a peripheral blood pressure, such as a radial arterial blood pressure measured by a wearable device, to a heart-level blood pressure, i.e. a brachial arterial blood pressure for clinical use, and performs feature fusion and a feature conversion on the feature information of each brachial arterial blood pressure value, so that the determined target brachial arterial blood pressure value becomes more accurate, and improves the accurac…
