Abstract: An electronic device is provided. The electronic device includes a housing, a first photoplethysmography (PPG) sensor that is exposed to a first portion of the housing and faces a first body portion of a user to measure a pulse wave, a wireless communication circuit that is positioned within the housing, a processor that is positioned within the housing and is operatively connected with the first PPG sensor and the wireless communication circuit, and a memory that is positioned within the housing and is operatively connected with the processor. The memory stores instructions that, when executed, cause the processor to monitor a first pulse signal measured by the first PPG sensor, to receive a second pulse signal measured by an external electronic device by using the wireless communication circuit, and to provide a first blood pressure value by using a pulse wave velocity (PWV) algorithm.
