ABSTRACT:
A portable device having a biosignal measuring instrument includes: at least one first electrocardiogram signal sensor portion on a first surface of the portable device that contacts a first hand of a user, to measure a first electrocardiogram signal of the user; at least one second electrocardiogram signal sensor portion on a second surface of the portable device that contacts a wrist of a second hand of the user, to measure a second electrocardiogram signal from the wrist; a pulse waveform sensor on the second surface and in parallel with the second electrocardiogram signal sensor portion, to sense a pulse waveform from the wrist; a waveform controller generating an electrocardiogram waveform of the user from the measured first electrocardiogram signal and second electrocardiogram signal, generating a pulse waveform of the user from the sensed pulse waveform, and detecting at least one characteristic point of the pulse waveform by referring to the electrocardiogram waveform; and an output portion providing a result of the pulse wave analysis based on the at least one detected characteristic point of the user.
