Abstract:The Electrocardiogram (ECG) is undoubtedly the most used biological signal in the clinical world and it is a means for detection of several cardiac abnormalities. Pattern recognition, diagnostic classification of ECGs constitutes an interesting application of Artificial Neural Networks (ANNs). This paper illustrates the ability of a feed-forward back propagation using Neural Network for classify unknown ECG waveforms keen on one of the 4 discrete class. Out of the 4 classes, 3 of them correspond to abnormal EC… Show more
“…Ashutosh Gupta et al [21] have presented a non-linear neural network model for ECG classification. They have used two layered feed-forward back-propagation network with sigmoid output neurons in order to grade the input ECG dataset into four different signal classes: Myocardial Ischemia Qibin Zhao and Liqing Zhang [22] have used support vector machine (SVM) with Gaussian kernel to classify different ECG heart rhythm.…”
Abstract-Accurate analysis of ECG signal is of utmost importance as the amplitudes and intervals value of ECG provide information about proper functioning of heart of every human. Therefore there have been numerous researches going on for analysis of ECG signal. In this paper we discuss about various methods that are used to extract features of ECG signal and further classify them into various disorders based on the features extracted. We also discuss about various preprocessing methods to remove base line wander and other contaminants from the ECG signal. Most researchers take input signal from MIT-BIH Data base. Performance of preprocessing is measured using Signal to Noise Ratio (SNR) and performance of feature extraction methods and classification is measured using Sensitivity and Positive Predictivity.keywords-ECG signal, MIT-BIH Data base, feature extraction, abnormalities.

“…For convenience, Person_01/rec_1 record of MIT-BIH ECG ID database has been renamed as P1(1). The 72 extracted features are subjected to a two layered feed forward network, with Sigmoid hidden and Softmax output neurons, which can classify vectors arbitrarily well, given enough neurons in its hidden layers [24]. From Figure 9, the 72 generated features were taken as input.…”

Person identification is an essential task in defense and forensic applications such as surveillance and criminal investigation activities. Studies conducted in the past included different types of regular biometric traits, namely fingerprint, face, iris, and voice have a limitation of falsification, and they do not fit guarantee of liveness of the subject. In this context, Electrocardiogram based Biometric recognition is an alternative solution, where the security of the information is very high level. This research aims to provide with a complete systematic approach to ECG based Biometric recognition, which contains primarily the processing of raw signal through noise elimination filters and a time domain analysis is carried for all ECG characteristic waves detection. Subsequently, an effective feature extraction method for ECG is developed, which extracts six best P-QRS-T fragments based on priority and their positions are normalized. Also, 72-time domain features are calculated. These features are formed into feature vector corresponding to each signal separately for both train and test data sets. To analyze the performance of the system, the feature vectors are trained with various Machine learning classification algorithms like Artificial Neural Network (ANN), Support Vector Machine (SVM) and K-Nearest Neighbor (KNN). Finally, the proposed system is tested with a challenging, public available MIT-BIH ECG-ID Database. A comparative analysis using performance parameters is made with different classifiers, and the obtained results show that SVM classifier provides 93.709% overall classification accuracy when compared to previous literature.
