Electrocardiogram (ECG) signal analysis has become significant in recent years as cardiac arrhythmia shares a major portion of all mortality world-wide. To detect these arrhythmias, computer-assisted algorithms play a pivotal role as beat-by-beat monitoring of holter ECG signals is required. In this paper, a morphological arrhythmia classification algorithm has been proposed to classify seven different ECG beats, namely Normal Beat (N), Left Bundle Branch Block Beat (L), Right Bundle Branch Block Beat (R), Atrial Premature Contraction Beat (A), Premature Ventricular Contraction Beat (V), Fusion of Normal and Ventricle Beat (F) and Pace Beat (P). A novel feature set of 25 attributes has been extracted from each ECG beat and ranked using the Fuzzy Entropy-based feature
selection (FEBFS) technique. In addition, two distinct classifiers, support vector machine with radial basis function as the kernel (SVM-RBF) and weighted K-nearest neighbor (WKNN), are used to categorize ECG beats, and their performances are also evaluated after adjusting vital parameters. The performance of classifiers is compared for four different ECG beat segmentation approaches and further analyzed using three similarity measurement techniques and two fuzzy entropy methods while feature selection. The classifier results are also cross-validated using a 10-fold cross-validation scheme, and the MIT-BIH Arrhythmia Database has been used to validate the proposed work. After selecting 21 highly ranked features, WKNN achieves the best results with the nearest neighbor value K=3 and cityblock distance metrics, with Average Sensitivity (Sen) = 94.89%, Positive Predictivity (Ppre) = 97.13%, Specificity (Spe)= 99.72%, F1 Score = 95.95%, and Overall Accuracy (Acc) = 99.15%.The novelty of this work relies on formulating a unique feature set, including proposed symbolic features, followed by the FEBFS technique making this algorithm efficient and reliable for morphological arrhythmia classification. The above results demonstrate that the proposed algorithm performs better than many existing state-of-the-art works.

“…[44][45][46] This operation uses a few parameters, which not only simplifies the training process but also speeds up the network. [47,48] But in reality, there are not a large number of parameters to design a more complex network. As mentioned in the above section, higher-order spectra are more suitable for non-Gaussian heart sound signals.…”
Section: The Designed Mcnn For Heart Sounds Classificationmentioning
This paper proposes a pre‐processing method for heart sound screening and extracts the high‐order spectral feature of phonocardiogram. Moreover, a multi‐convolutional neural network (mCNN) is constructed to achieve the classification of normal, aortic stenosis, mitral regurgitation, mitral stenosis, and mitral valve prolapse. First, the heart sound recordings are down‐sampled, denoised by wavelet transform, and normalized. Second, a new heart sound screening algorithm is proposed. The waveform of the heart sound recording is segmented and saved as an image which is performed by the gray‐scale processing to calculate the amplitude of the heart sound. The extremely noisy heart sound segments are screened out based on the amplitude information, and the remaining heart sound segments are spliced as pure heart sound recordings. After 50% superposition segmentation of the heart sound recordings, high‐order spectral features are extracted and image data are stored. Finally, a 34‐layer mCNN is specifically designed to boost the performance of heart sound classification through multi‐layer dimensionality reduction. Experimental results show that the proposed method has superior performance compared with the existing one. For the two‐category dataset, the accuracy with and without PCG screening is 97.99% and 99.42%, respectively. For the five‐category dataset, the average accuracy is 99%.

Electrocardiogram (ECG) monitoring is now becoming part of everyday health life. Through ECG characteristics such as patient's heartbeats, heart conditions, and heart disease can be analyzed. This paper presents the design and implementation of a system for analyzing and filtering the ECG signal and allowing its remote monitoring based on the use of deep learning algorithms, this algorithm is Convolution Neural Network (CNN), where the network was built in MATLAB and training using the dataset (PhysioNet 2017). when, the ESP NODE MCU microcontroller was used with the AD8232 sensor in designing a system that records the ECG signal from the patient in real time and filtering it using FIR filter that will be designed in MATLAB, then transmits it to the network that has been trained to be classified as whether it is normal or abnormal. Then, this result is transmitted locally to be displayed in monitoring side, the results showed high accuracy in classifying the signal and in filtering different Noise, as well as its speed in responding to a change in the condition of the signal and giving a warning to the observer. This contributes to speeding up the detection of the deterioration of the patient's condition in a timely manner.
