Abstract :
This paper proposed a new design of the mathematical model for ECG waveform using kernel function. The continued standard ECG signal will be converted to the discrete time signal or original ECG data. After that the original ECG data will be changed to the kernel ECG data by kernel function. Then the kernel ECG data will be converted to the polynomial equations or mathematical model using discrete least square technique. At the time this will be the complete mathematical model of ECG equations and will be used to implement the ECG simulator with high resolution and low memory storage. For the accuracy of the ECG signals that are implemented by mathematical models with ECG simulations is presented in a PRD (percent root mean square difference).
