摘要：The present invention proposes a relaxation state evaluation system andmethod and a computer program product thereof. The method comprises steps:measuring ECG data of a user; analyzing the ECG data to generate a first, second, thirdand fourth parameters, wherein the first parameter is the short-scale entropy slope ofthe user before cardiovascular disease treatment (CVDT); the second parameter is thedifference of the post-CVDT and pre-CVDT mean RR intervals; the third parameter is thelogarithm of the variance of the pre-CVDT high frequency NN intervals; the fourthparameter is the logarithm of the ratio of the variances of the pre-CVDT low frequencyand high frequency NN intervals; working out an evaluation index, which is a function ofthe abovementioned parameters; and evaluating the relaxation state of the user, whereinthe user is determined to be in a relaxation state if the evaluation index is over athreshold.
