A method for physiological signal analysis and its system and a computer program product storing a physiological signal analysis program are provided. Physiological signals of a subject are collected for a user to provide a detection opinion for the physiological signals in order to generate syndrome recognition parameters and syndrome weight parameters such that the collected physiological signals are analyzed and determined. The invention performs detection determination by means of combining the physiological signals of the subject and referencing to an analysis opinion from the user. Therefore, an output detection result may be believed by both doctors and patients with effectively improved accuracy of analysis result to improve the efficiency of the user in diagnosis and treatment.一種生理訊號分析方法及其系統與內儲生理訊號分析程式之電腦程式產品,係透過收集受測者之生理訊號,俾供使用者針對該生理訊號提供檢測意見,藉此以產生病症辨識參數及病症權重參數,以利用該病症辨識參數及病症權重參數針對所收集到的生理訊號進行分析判定。藉此,本發明透過結合分析受測者的生理訊號及參酌使用者分析意見的方式進行檢測判定,故所輸出的檢測結果不但更能取信於醫患雙方,亦能有效提升系統分析結果之準確性以輔助使用者提升診療工作的效率。
