A heart state monitor method is proposed. The pressure signal of a life body is measured and then performed by Fourier transform analysis. Next, the frequency domain data of the pressure signal are converted into a power spectral density (PSD). A heart beat noise index of the life body is then obtained according to the PSD. Finally, the heart state of the life body is diagnosed according to the heart beat noise index. The heart beat noise index may be quickly discriminated to let the life body and medical staffs grasp the current heart state of the life body at any time.
