Abstract: Methods, systems, and devices for identifying representative photoplethysmogram (PPG) pulses are described. A method may include acquiring a first set of PPG pulses from a user via a wearable device. The method may include comparing a set of morphological features of the first set of PPG pulses, and determining one or more PPG profiles for the user, where the one or more PPG profiles each include a set of morphological value ranges for the set of morphological features. The method may include acquiring a second set of PPG pulses from the user via the wearable device, and determining that one or more PPG pulses from the second set of PPG pulses match the one or more PPG profiles. The method may include determining one or more physiological metrics associated with the user based on the one or more PPG pulses matching the one or more PPG profiles.
