PROBLEM TO BE SOLVED: To solve a problem that a conventional heart condition monitoring system using a pulse wave signal is an expensive device in which internal components are complicated and precise parts, and to easily detect an abnormal state of the heart. I will provide a. SOLUTION: A cardiac abnormality state detection device 1 uses a pulse pressure wave used for blood pressure measurement, pays attention to a difference in the shape of a pulse pressure waveform that changes due to some abnormality in the heart, and converts the pulse pressure waveform into a high-speed Fourier transform or the like. It monitors the waveform rate, strain, and sharpness, which are statistics of waveform data of the frequency spectrum of signal processing and pulse pressure waves, and detects cardiac abnormalities such as atrial fibrillation and ventricular extrasystole.
