Abstract

Systems and methods for performing a blood pressure measurement are provided. An example method includes simultaneously recording, by a wearable device, an electrocardiogram (ECG) and photoplethysmogram (PPG). PPG is measured at a blood artery. The method also includes analyzing ECG and PPG to determine a pulse transit time (PTT), a pulse rate (PR), and a diameter parameter. The diameter parameter includes a diameter of the blood artery or a change thereof. The method also includes determining, based on PTT, PR, and the diameter parameter, a blood pressure (BP) using a pre-defined model. The pre-defined model establishes a relationship between PTT, PR, the diameter parameter, and BP. The pre-defined model may be trained using statistical data obtained in a calibration process. The statistical data includes PTT, PR, and the diameter parameter measured with the wearable device and corresponding values of BP measured with an external device.
