To assess deep learning techniques frequently utilized in the literature, we analyzed ECG data from five separate classes containing 109,446 beats collected from the MIT-BIH arrhythmia database and the PTB Diagnostic ECG Database. The data were recorded at 360 samples per second per channel, using an 11 bit resolution and a 10 mV range. The process selects a single lead in the dataset, and all segments use the Z-score normalizing method (Acharya et al., 2017b). S. T. Prasad, S. Varadarajan, and S.

The performance is recorded after every iteration and integrated into one final confusion matrix at the end of the 10th iteration. This means that the test dataset is still unbalanced and maybe the reason for the high accuracy value. The features obtained by ICA are used as the training set. In August, 1989, we produced a CD-ROM version of the database. Kuznetsov and Moskalenko [24] developed a vibrating car encoder to generate an ECG signal for a heart cycle. Noise is added to the data to mimic the external random processes that can interfere in the data recording process. Comp. 16, 275287.
