Abstract—In this paper a kind of ECG signal automatic segmentation algorithm based on ECG fractal dimension trajectory is put forward. First, the ECG signal will be analyzed, then constructing the fractal dimension trajectory of ECG signal according to the fractal dimension trajectory constructing algorithm , finally, obtaining ECG signal feature points and ECG automatic segmentation will be realized by the feature of ECG signal fractal dimension trajectory and the feature of ECG frequency domain characteristics. Through Matlab simulation of the algorithm, the results showed that by constructing the ECG fractal dimension trajectory enables ECG location of each component displayed clearly and obtains high success rate of sub-ECG, providing a basis to identify the various components of ECG signal accurately.
