Abstract
Provided is a pulse wave propagation detection system including an electrocardiographic signal detection unit, and an eyeground image detection unit for detecting an eyeground image in synchronization with an electrocardiographic signal detected through the detection unit, which system further includes a correlation unit for correlating a change in the diameter of an eyeground vein—which diameter is measured, at the optic papilla, by use of an eyeground image synchronized with an arbitrary electrocardiographic signal—with the state of pulse wave propagation through an intracerebral blood vessel or with the state of sclerosis of a capillary artery.
Claims20
A pulse wave propagation detection system comprising
- electrocardiographic signal detection means for detecting a first electrocardiographic signal at a first point, and for detecting a second electrocardiographic signal at a second point;
- and
- eyeground image detection means for detecting eyeground image data in synchronization with the first time point and the second time point, and for detecting pulse wave propagation in an intracerebral blood vessel on the basis of a change in a diameter of an eyeground vein, the diameter being measured at a target site of the eyeground image data synchronized with the first electrocardiographic signal detected at the first point and the second electrocardiographic signal detected at the second point.
