ECG or electrocardiogram is an electrical signal which is generated by our heart. It is the cardiac electrical activity that provides important information about heart conditions [2]. ECG is very popular to identify heart illnesses like arrhythmia, chest pain, heart abnormalities, measuring heart rate, etc. In the past, till now ECG is the primary technique to detect heart illness in medical. ECG is a non-invasive technique. A survey World Health Organization says that heart diseases are the main reason for most deaths worldwide. In most cardiovascular diseases, arrhythmia is the most common. For this ECG is very much famous in medical studies. The study of an individual ECG beat can provide meaningfully correlated clinical information for the automatic ECG recognition of an ECG signal but it is difficult to investigate more ECG signals of different patients because of their different physical conditions. So here the main problem to investigating an ECG signal is that it can be different in every person. Suppose two different types of diseases have the same type of properties in an ECG signal. Even sometimes different patients have the same type of ECG pattern graph. These are the main difficulties in diagnosing an ECG signal. Many methods of feature extraction and classification have been proposed but some of the techniques  remain to be improved. In this paper first of all we make our database with the help of the MIT-BIH database. After preprocessing and segmentation we decompose the signal by wavelet packet decomposition. Then calculate the entropy from the decomposed coefficients and extract the features.
