Abstract: A wearable device can be used for hypertension monitoring. The wearable device can include a motion sensor and an optical sensor. The data from the sensors can be processed in the wearable device and/or by another device in communication with the wearable device to provide an early screening for undiagnosed hypertension. If the screening estimates undiagnosed hypertension for a user, the user can then be notified to seek a proper hypertension diagnosis. The hypertension monitoring can include a first stage to estimate one or more short-term hypertension scores or parameters. The hypertension monitoring can also include a second stage to estimate a long-term hypertension score using accumulated short-term scores/parameters to estimate hypertension.

Abstract: This relates to methods for measuring irregularities in a signal and corresponding devices. The devices can include a PPG sensor unit configured to detect multiple occurrences of a given event in the measured signal(s) over a sampling interval. In some instances, the device can register the occurrences of the events. In some examples, the device can include one or more motion sensors configured to detect whether the device is in a low-motion state. The device may delay initiating measurements when the device is not in a low-motion state to enhance measurement accuracy. Examples of the disclosure further include resetting the sample procedure based on one or more factors such as the number of non-qualifying measurements. In some examples, the device can be configured to perform both primary and secondary measurements, where the primary measurements can include readings using a set of operating conditions different from the secondary measurements.
