Abstract :
A new technique for ECG character points measurement is presented. The linear approximation distance thresholding (LADT) and line segment clustering (LSC) technique are combined to process the ECG signal, and recognize the important points of one beat ECG signal. In this study, several character points, such as R peak and T peak are recognized by the technique. The results of LSC technique are compared to manual results. Simulation signals with different SNR (5%, 10%, 15%, 20%, 25%, 30%) white noise and from 10 healthy volunteer 12-lead ECG signals are used to evaluate the system. The error of noisy simulation signal (SNR:30%) is under 7 points. The error of real signal is under 4 points
