ECG machine records the electrical activity of the heart with the assistance of electrodes placed on the patient\u2019s body. Qualitative characterization of ECG signal reflects its sensitiveness towards distinct artifacts that resulted in low diagnostic accuracy and may lead to incorrect decision of the clinician. The artifacts are removed utilizing a robust noise estimator employing DTCWT using various threshold values and functions. The segments and intervals of ECG signals are calculated using the peak detection algorithm followed by particle swarm optimization (PSO) and the proposed optimization technique to select the best features from a considerable pool of features. Out of the 12 features, the best four features are selected using PSO and the proposed optimization technique. Comparative analysis with other feature selection methods and state-of-the-art techniques demonstrated that the proposed algorithm precisely selects principle features for handling the ECG signal and attains better classification utilizing distinctive machine learning algorithms. The obtained accuracy using our proposed optimization technique is 95.71% employing [Formula: see text]-NN and neural networks. Also, 4% and 10% improvements have been observed while using [Formula: see text]-NN over ANN and SVM, respectively, when the PSO technique is executed. Similarly, a 14.16% improvement is achieved while using [Formula: see text]-NN and ANN over the SVM machine learning technique for the proposed optimization technique. Heart rate is calculated using the proposed estimator and optimization technique, which is in consensus with the gold standard. <\/jats:p>","DOI":"10.1142\/s0219467820500230","type":"journal-article","created":{"date-parts":[[2020,8,3]],"date-time":"2020-08-03T09:10:35Z","timestamp":1596445835000},"page":"2050023","source":"Crossref","is-referenced-by-count":24,"title":["Novel Cardiac Arrhythmia Processing using Machine Learning Techniques"],"prefix":"10.1142","volume":"20","author":[{"given":"Navdeep","family":"Prashar","sequence":"first","affiliation":[{"name":"Department of Electronics & Communication Engineering, Bahra University Shimla Hills, Kandaghat, Solan 173234, Himachal Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meenakshi","family":"Sood","sequence":"additional","affiliation":[{"name":"Department of CDC National Institute of Technical Teachers Training and Research, Chandigarh Sector-26, Chandigarh 160019, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shruti","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of Electronics & Communication Engineering, Jaypee University of Information Technology, Kandaghat, Solan 173234, Himachal Pradesh, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2020,7,31]]},"reference":[{"issue":"17","key":"S0219467820500230BIB001","doi-asserted-by":"crossref","first-page":"2721","DOI":"10.1161\/01.CIR.0000145144.56673.59","volume":"110","author":"Drew B.
