Abstract: A system provides ECG monitoring for a user. The system includes an in-ear device and processor. The in-ear device includes in-ear electrodes that capture electrical signals of the pulses of the heartbeat of the user from within the user's ear canal, and an out-of-ear electrode that does not contact any surface of the user's ear or ear canal, and captures electrical signals of pulses of the heartbeat of the user from a fingertip of the user when the user contacts the out-of-ear electrode with their fingertip. The processor generates ECG data using captured electrical signals responsive to a determination that the user has positioned a finger to touch the out-of-ear electrode on the in-ear device. This configuration allows the out-of-ear electrode to, when touched by the user's fingertip, effectively function as an arm electrode, allowing for ECG data to be measured from two different angles, through a path that passes through the user's heart.

Abstract: Methods, systems, and media for determining blood pressure measurements are provided. In some embodiments, a method for determining blood pressure measurements comprises: obtaining a set of photoplethysmography (PPG) signals using a wearable device worn by a user; determining that a blood pressure of the user is being measured by a device unassociated with the wearable device based at least in part on the set of PPG signals; responsive to determining that the blood pressure of the user is being measured by the device unassociated with the wearable device, obtaining an indication of a blood pressure measurement obtained by the device unassociated with the wearable device; and storing the obtained indication of the blood pressure measurement for future use by the wearable device.
