Fig. 1. A diagram of the arrhythmia classification system. The first two steps of a such classification system (ECG signal preprocessing and heartbeat segmentation) have been widely explored in the literature [2], [3], [4], [5], [6]. The techniques employed during the preprocessing step ...
The present study examines the role of feature selection methods in optimizing machine learning algorithms for predicting heart disease. The Cleveland Heart disease dataset with sixteen feature selection techniques in three categories of filter, wrapper,

Dead 15 (10%) 28 (17%) A report on NYHA functional class was missing at one or more time points in 7 patients randomly assigned to usual care, 14 patients to nurse telephone support, and 15 patients to home telemonitoring. Percentages shown are percentage of those in whom data on NYHA...
Electrocardiogram (ECG) signals represent the electrical activity of the human hearts and consist of several waveforms (P, QRS, and T). The duration and shape of each waveform and the distances between different peaks are used to diagnose heart diseases.
Diagram of the proposed general approach and its implementation in the congestive heart failure (CHF) readmission case. The upper part of the figure is the proposed general approach steps and the lower part is for their CHF readmission counterparts. The three steps of the approach, namely pre-pr...
It can be seen from Figure 9 that the re-parameterization did not change the shape of the model, and then the FPS broken line diagram of ten consecutive times in both cases was drawn. As shown in Figure 10, it can be seen that the re-parameterization improved the FPS of the program ...
FIG. 2 is a schematic cross-sectional diagram of the University of Utah electrohydraulic heart. This heart includes shells 50 and 52 with a pump motor 34 interposed between them. In this type of heart, a motor 20 is used to pressurize silicon oil in regions 22 and 24 on the undersides...
2096Accesses 13Altmetric Metrics Abstract A deeper knowledge of the dynamic transcriptional activity of promoters and enhancers is needed to improve mechanistic understanding of the pathogenesis of heart failure and heart diseases. In this study, we used cap analysis of gene expression (CAGE) to identi...
