An electronic device is disclosed. The electronic device of the present disclosure comprises: a sensor； a communication unit； and a processor which receives first and second biosignals sensed at a first measurement part from the sensor, receives first and second biosignals sensed at a second measurement part from an external electronic device through the communication unit, synchronizes the second biosignal received from the sensor and the second biosignal received from the external electronic device on the basis of the first biosignal sensed at the first measurement part, and obtains a third biosignal on the basis of the synchronized second biosignals, wherein the rate at which the first biosignal propagates from a predetermined body organ is faster than the rate at which the second biological signal propagates.
