  • Comparison of Efficientnet B3 and Inception V3 Architecture Performance in Heart Disease Arrhythmia Image Classification
    J. Prayoga, Melinda Melinda, Teuku Yuliar Arif, Herlina Dimiati
    International Conference on Computer and Communication Engineering Iccce, 2025
    Early detection of cardiac arrhythmias is essential to prevent complications and improve patient outcomes. The ECG is a key diagnostic tool, but manual analysis requires expertise and is prone to error, necessitating automated classification. This study compares the performance of two deep learning models, Inception V3 and EfficientNet B3, for classifying arrhythmias using the MIT-BIH Arrhythmia Database, which contains 48 ECG recordings from 47 individuals aged 23–89. The ECG signals were denoised using a bandpass filter, features extracted with Discrete Wavelet Transform (DWT), and then transformed into vector images for input to the models. Results show that Inception V3 outperformed EfficientNet B3, achieving 99.28% accuracy, 99.72% precision, 98.89% sensitivity, and a 99.30% F1-score, compared to EfficientNet B3's 98.12% accuracy, 98.06% precision, 98.33% sensitivity, and 98.20% F1-score. These findings highlight Inception V3's superior performance and its strong potential in supporting automated ECG-based arrhythmia diagnosis in clinical settings.
  • ECG Atrial Fibrillation Signal Classification Method Based on Discrete Wavelet Transform (DWT) and DenseNet-121
    Muhammad Irhamsyah, Melinda Melinda, Jihan Alifa, J. Prayoga, Yulita Hanum P. Iskandar
    2024 10th International Conference on Smart Computing and Communication Icscc 2024, 2024
    Atrial Fibrillation AF is one of the most common dysrhythmias. It affects almost all patients with symptoms of heart disease, with a percentage of around 1% to 2%, which increases with age and is more common in women. The need for the application of technology in medical devices, especially electrocardiograms (ECG), can slow down the treatment of patients, especially those with symptoms of heart disease. This research aims to apply deep learning in signal processing to analyze the performance of classification results. Therefore, signal processing methods such as extraction and classification can be used to determine a diagnosis by detecting heart rhythm abnormalities. This study will combine signal preprocessing methods with Bandpass Filter and Windowing, feature extraction using Discrete Wavelet Transform (DWT), and classification with the DenseNet-121 CNN architecture to analyse the proposed method compared to the previous research. A bandpass filter removes noise at too large frequencies, and then DWT reconstructs the signal to obtain a pattern that stores signal information. Next, windowing is carried out to increase the data with various variations of patterns so that Densenet-121 will more easily study signal patterns and classify them into 2 classes, namely NORMAL and AF. The dataset used was from the MIT-BIH Atrial Fibrillation Database, with 17 ECG recordings for each patient. The performance produced in this research is an accuracy of 94.67%.
