“…The efficiency of the given R-peaks finding technique is compared with other exiting methodologies and summarized in Table 2. It shows the significant improvement compared with the techniques which use the non-linear filtering in their preprocessing stage [15][16][17][18]. and comparable results with the Fractional Fourier transform [14], S-transform [19], and wavelet transforms [20].…”

The exact discovery of R-peak becomes very much crucial while extracting prominent features from Electrocardiogram (ECG) signal. However, identification of R-peaks precisely becomes more challenging due to contamination of noise and fragmented QRS complexes. This paper presents an improved method of marking R-peaks. Initially, an efficient Fourier Decomposition Methodology (FDM) is used for removing noise. The accuracy of finding R-peaks can be improved by enhancing the QRS complexes using Teager Energy Operator. Hilbert Transform and Zero Cross Detector (ZCD) are used for marking the R-peaks. The MIT-BIH arrhythmia database is used for validating the proposed scheme and attained 99.97% accuracy, 99.98% of sensitivity and 99.98% of positive predictivity. The findings proved that proposed method is superior as compared to the proven techniques in the literature.

“…These are optimum compared with standard FIR filters. Nonlinear energy operator and simple thresholding technique has also been used for efficient marking of R-Peaks [15][16][17]. Fractional Stock well transform is a combination of fractional fourier transform and Stockwell transform has been used by Bajaj and Kumar [18].…”

“…The Teager operator is a nonlinear operator that mainly shows the frequency and instantaneous changes of the signal amplitude and is very sensitive to subtle changes. Although the Teager operator was first proposed for modeling nonlinear speech signals, it was later widely applied in ECG and EEG research [13]. Its expression is as follows:…”

The main characteristics of three approaches to cardiac care using public data networks are presented. All efforts were addressed to get minimum-cost solutions for low-budget public health systems. The first solution was developed to follow-up arrhythmic patients between medical consultations, setting a more closed patient-physician relationship, and a daily recording of cardiac rhythm changes. It is based on a personal battery-powered device for one-channel ECG recording, minimizing electrode setting and operation complexity. An ECG recording taken daily allows a detailed analysis anytime without the patient’s traveling to a health institution. A second solution was aimed at monitoring high-risk cardiac patients. A 24-h portable device capable of monitoring heart rate and sudden falls, typically associated with cardiac syncope, was developed. When any cardiac event or fall is detected, an urgent message is sent to relatives and the medical emergency care system asking for help. The third system implemented is oriented to the study of different cardiac parameters in people who suffer from heart disease or in those who are prone to suffering from it. Twelve-lead ECG is recorded periodically by each patient and trend graphics reflect ECG parameters strongly associated with cardiac disturbances, such as sudden death and ischemia. This approach allows the detection of the first troubling electrocardiographic deviations, making possible early medical intervention.

The ability of the human autonomic nervous system to regulate can be assessed and judged by HRV analysis. The purpose of this paper is to examine the HRV of college students in the quiet condition and the heart rate variation of the recovery process following long-distance running, and heart rate change from rock music to a light music environment were compared and analyzed. By studying the control group consisting of collegiate and non-varsity sports teams as objects of investigation, and the effects of exercise and noise on HRV were assessed. For the purposes of this paper, the ECGs of experimenters in different states were collected, and the R-R interval was extracted as the primary research data. First, the HRV parameters MHP, HR, SDNN, RMSSD, pNN50 in the time domain were calculated using the R-R interval and then the HRV in the frequency domain was analyzed by scatterplot analysis. Based on these results, the average specificity of the five indicators was 88.74%, and the sensitivity was 76.54%. In conclusion, this study demonstrates that HRV of collegiate sports teams in the process of sport recovery and music slowing is stronger than that of non-varsity sports teams. And exercise may improve the balance of sympathetic and parasympathetic nerves in the human body.
