    Abstract: An electronic device includes a processor and memory, wherein the memory stores instructions that, when executed by the processor, control the electronic device to: determine a pulse arrival time (PAT) value, a heart rate (HR) value, and a pulse transit time (PTT) value from the second data, calculate a first blood pressure value (BP1) and a second blood pressure value (BP2) by applying the determined values to pulse wave velocity (PWV) algorithms of Equations 1 and 2, wherein BP1≅a1PAT+b1HR+c1 . . . Equation 1, BP2≅a2 ln(PTT)+b2 . . . Equation 2 in Equations 1 and 2, a1, a2, b1, b2, and c1 are constant values for matching blood pressure values measured during calibration with blood pressure values measured by a cuff hemodynamometer, determine a calibration time point based at least in part on a difference between the first blood pressure value and the second blood pressure value, and provide guide information related to the calibration time point through a user interface based at least in part on the determination.
