An Automatic Wavelet Transform Based ECG Detection Algorithm

The cardiovascular disease is one of the main diseases endangering human's life. ECG signal, or electrocardiogram, is a synthetic reflection of the heart electricity on body surface. Therefore, Clinical ECG examination has important significance in diagnosis of cardiovascular disease. In this paper, we conclude from former experiences in ECG Processing, and develop an automatically ECG analysis algorithm which is based on wavelet transform, aim to accurately locate the position of Q, R and S wave in a piece of ECG signal preparing for the following diagnosis of heart diseases.
