Result Analysis of Noise Removal in ECG Signal using Wavelet Decomposition Technique

Now-a-days Cardio vascular diseases become huge threat to the lifetime of human beings. ECG is one in all the simplest technique to give clear information about cardiac arrhythmia. The electro-cardiogram may be a technique of recording bioelectric currents generated by the heart that is useful for diagnosing several cardiac diseases. The feature extraction and denoising of ECG are extremely useful in cardiology. ECG may be a non-stationary signal and it is used for the first diagnosis of cardiac abnormalities like arrhythmia, MI and conduction defects. However the ECG signals usually contaminated by different noises. The ECG signal should be denoised to remove all the noises like Additive White Gaussian noises.
