Relationship analysis between BCG features and blood pressure

Hypertension, one of lifestyle-related diseases, is a cause of life-threatening diseases such as cerebral hemorrhage. In particular, non-dipper hypertension, in which blood pressure does not decrease during nighttime sleep, is considered to be a disease with a high risk. Blood pressure monitor using a cuff requires compression of the artery. It is difficult to measure without disturbing sleep. Therefore, we focused on the ballistocardiogram (BCG) based blood pressure estimation method that does not use a cuff. BCG is a biological signal that can be measured without attaching a sensor to the body. BCG is a biological signal composed of vibrations caused by heartbeat, and research on estimating relative blood pressure is attracting attention. In this study, we analyzed the relationship between features extracted from BCG and blood pressure.
