这是Simulink关于数据转换仿真模型。希望对初学者有用(This is the Simulink simulation model about the data transformation. Hope useful for beginners )

After we calculate the R peaks of the ecg signal, we identify different criteria : a) Heart rate. b) Regularity of the R-R peaks (Look at the R-R distances). 1. Regular (are they equidistant apart). 2. Irregular. c) Rhythm 1. Tachycardia ==> Fast. 2. Bradychardia ==> Slow. 3. Normal.
