TECHNIQUES FOR DETERMINING BLOOD PRESSURE BASED ON A RELATIVE TIMING OF PULSES

Methods, systems, and devices for determining blood pressure based on a relative timing of pulses are described. In some implementations, a system may include one or more wearable devices configured to measure heartbeats at different locations on the body of a user. The different locations may be different physiological locations (e.g., chest and finger/wrist), and/or different penetration depths at the same physiological location. The system may use the components of the wearable devices to acquire physiological data and to observe one or more heartbeats of the user over a time period. The system may compare pulse observation times observed at the different locations, and may determine a blood pressure metric for the user based on a relative timing of when heartbeats are observed at the different locations.
