Provided are a method and system for detecting information of brain-heart connectivity, the method comprising: obtaining moving images of a pupil and an electrocardiogram (ECG) signal from a subject; acquiring a pupil size variation (PSV) from the moving images by separating the moving images at a predetermined time range after R-peak of the ECG signal; extracting signals of a first period and a second period from the PSV; calculating alpha powers of the signals of the first and second periods at predetermined frequencies respectively.

Method and system for detecting information of brain-heart connectivity by using pupillary variation

Provided are a method and system for detecting time-domain cardiac information, the method comprising: obtaining moving images of a pupil from a subject; extracting a pupil size variation (PSV) from the moving images; calculating R-peak to R-peak intervals (RRIs) in a predetermined frequency range from the PSV; and obtaining at least one time-domain cardiac parameter by processing the RRIs.
