Abstract: Provided is a device and method for diagnosing a blood circulation disturbance. The device includes a measurement unit configured to measure a first signal and a second signal associated with a cardiac impulse of a patient at two different points in a body of the patient, a matching unit configured to match cycles of the first signal and the second signal, and a diagnosis unit configured to acquire reference points included in the matched cycles of the first signal and the second signal and to diagnose the blood circulation disturbance of the patient using a time difference between the reference points.

Abstract: The present invention relates to an apparatus for measuring blood circulation disorders, and a method therefor. The apparatus for measuring blood circulation disorders using a pulse wave transit time includes a measurement unit configured to measure a pulse wave and an electrocardiogram of a subject to be measured, a detection unit configured to detect time information of a peak value point of the electrocardiogram and a peak value point and a foot value point of the pulse wave, an operation unit configured to calculate an average pulse wave transit time using the time information of the peak value point of the electrocardiogram and the peak value point and the foot value point of the pulse wave and calculate a blood circulation disorder determination index using the average pulse wave transit time, and a diagnosis unit configured to diagnose a blood circulation disorder using the blood circulation disorder determination index.
