PPG signals in .MAT files

This information is related to the project "PPG-Based Cholesterol Assessment," which showcases different PPG signals along with the cholesterol levels of the subjects. The purpose is to validate techniques or tools for estimating total cholesterol levels in the blood using the PPG signal.本数据集关联于「基于光电容积描记法（Photoplethysmography，简称PPG）的胆固醇评估」项目，该项目展示了不同受试者的PPG信号及其对应的血清胆固醇水平。本数据集旨在验证基于PPG信号估算血液总胆固醇水平的相关技术与工具。
