Abstract: A cardiovascular health status evaluation system includes a sensing unit and a computing unit. The sensing unit is for measuring impulses of the cardiovascular circulation of a user. The computing unit is for calculating a standard deviation and an average of time intervals between the impulses in a unit time, and based on a change of a ratio between the standard deviation and average, evaluating the cardiovascular health status of the user. The evaluation index of the aforementioned system includes a personalized parameter (the average), thereby enabling a personalized comparison. A cardiovascular health status evaluation method is also disclosed herein.
