Many algorithms for PQRST feature extraction have been reported in the literature, especially algorithms for finding the QRS complex [Pahlm and Sornmo, 1984] [Hamilton and Tompkins, 1986]. In this section, only the feature extraction algorithm used i

MS-VAR模型，即马尔科夫状态转换的自回归模型是Hamilton (1989) 提出的，它是允许内在要素变化的特有的计量经济学模型。-MS-VAR model, the regression model Markov state transition is Hamilton (1989) proposed that the change is to allow the intrinsic elements of specific econometric model
