Abstract：Objective To study a scoring method for assessing function status of cardiovascular system quantitatively. Methods First, exercise heart rate variability (EHRV) was obtained from the primary dynamic electrocardiogram (ECG) recorded during exercise testing. Then appropriate entropy, relative complexity, and other three parameters extracted from poincare dispersed-dot plot were extracted from the EHRV. Discriminant analysis was used to classify two extreme groups.Results Based on the values of two groups from the discriminant formula, a scoring formula was proposed and four ranks were divided according to different score domains. A novel scoring method was established. To validate the proposed scoring method, 60 middle-aged hypertensives, 50 elder subjects and 110 young healthy subjects were examined and scored. Conclusion Scores of 220 subjects are consistent with their real health status. The proposed scoring method reflects the status of the subject's cardiovascular system effectively.
