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.

ＢＰ神经网络算法是在ＢＰ神经网络现有算法的基础上提出的，是通过任意选定一组权值，将给定的目标输出直接作为线性方程的代数和来建立线性方程组，解得待求权，不存在传统方法的局部极小及收敛速度慢的问题，且更易理解。(Back Propagation ａｒｔｉｆｉｃｉａｌ ｎｅｕｒａｌ ｎｅｔｗｏｒｋｓ)
