| Objective: This study intends to explore the abnormal sound waves of rough pulse in patients with stable coronary heart disease.Methods: In this study,the sonic pulse detection system was used to collect the rough pulse low-frequency audible sound waves of patients with stable coronary heart disease and the pulse low-frequency audible sound waves of relatively healthy people for comparative analysis.Explore whether the rough pulses of stable coronary heart disease patients have abnormal low-frequency audible sound waves,and perform wavelet analysis and multi-scale entropy analysis to extract pathological information contained in them.The pulse pressure waves of the two groups of subjects were collected with the Dao sheng four diagnostic instrument,and the pressure wave pulse were compared.Compare the pulse sound wave with the pressure wave and observe the difference between the two.Results:1.The location of abnormal low-frequency audible sound waves in patients with stable coronary heart disease: Compared with the relatively healthy group,more stable low-frequency audible sound waves appear in the third layer of the lower part of left cun pulse.2.Intuitive analysis: Compared with the original pulse map of the pressure wave pulse,the original pulse map based on the sound wave pulse diagnosis detection system can intuitively analyze the two groups of research objects.3.Wavelet analysis: Relatively healthy people often have high-frequency bands on the d1-d5 scale,while patients with stable coronary heart disease rarely have high-frequency bands on the d1-d5 scale.The difference between the two groups has statistical significance.4.Multi-scale entropy analysis: the abnormal coronary low frequency audible sound waves in patients with stable coronary heart disease are more complicated than those in relatively healthy people.The difference between the two groups is statistically significant.Conclusion: The rough pulse may be abnormal low-frequency audible sound wave. |
