Abstract:
In this paper, an algorithm with precise location and high detection rate is introduced. The modulus maxima of wavelet transform are applied to the singularity detection for ECG signal, and thus P wave, T wave and QRS waves can be well detected. Continuous wavelet transform with Mexican hat function is adopted to compute the modulus maxima under MATLAB6.5. The algorithm proves effective and reliable through the tests for the data form MIT-BIH database.
