APPARATUS FOR DIAGNOSING BLOOD CIRCULATION DISORDERS BY USING PULSE TRANSIT TIME, AND METHOD FOR DIAGNOSING BLOOD CIRCULATION DISORDERS BY USING SAME

摘要

The present invention relates to an apparatus for diagnosing blood circulation disorders by using pulse transit time, and a method for diagnosing blood circulation disorders by using the same. The apparatus for diagnosing blood circulation disorders by using pulse transit time comprises: a measurement unit for measuring the electrocardiogram (EKG) and pulse wave of a subject to be measured; a detection unit for detecting time information with respect to any one point in the QRS section from the Q wave point to the S wave point of the measured EKG, and the peak value point and/or foot value point of the pulse wave; a calculation unit for calculating the mean value of pulse transit time by using the detected time information, and calculating a first discrimination index for determining whether there are vascular diseases by using the mean value of pulse transit time, and/or a second discrimination index for determining whether the type of vascular diseases is a cardiovascular disease group or a cerebrovascular disease group; and a diagnosis unit for diagnosing, by using the first and/or second discrimination indices, the blood circulation disorders of the subject to be measured. Therefore, the present invention: can non-invasively measure blood circulation disorders at low cost since the risk of vascular diseases can be predicted by measuring a pulse wave and EKG; can be utilized in the first screening of a normal group and a disease group through a simple measurement of pulse transit time; and can be applied in various areas such as a medical check-up at hospitals, wellness platforms and other personal healthcare programs.
