Abstract

Sudden cardiac death and arrhythmia account for a large percentage of all deaths worldwide. Electrocardiography is essential in the clinical evaluation of patients who have heart disease. Through the electrocardiogram (ECG), medical doctors can identify whether the cardiac muscle dysfunctions presented by the patient have an inflammatory origin and diagnose early serious diseases that primarily affect the blood vessels and the brain. The basis of arrhythmia diagnosis is the identification of normal and abnormal heartbeats and their classification into different diagnoses based on ECG morphology. Traditionally, ECG signals are classified manually, requiring experience and great skill, while being time-consuming and prone to error. Thus, machine learning algorithms have been widely adopted because of their ability to perform complex data analysis. The objective of this study is to develop a classifier capable of classifying a patient’s ECG signals for the detection of arrhythmia in clinical patients. We developed a convolutional neural network (CNN) with long short memory (LSTM) to identify five classes of heartbeats in ECG signals. Our experiment was conducted with ECG signals obtained from a publicly available MIT-BIH database. The number of instances was even out to five classes of heartbeats. The proposed model achieved an accuracy of 98.12% and an F1-score of 99.72% in the classification of ventricular ectopic beats (V), and an accuracy of 97.39% and an F1-score of 95.25% in the classification of supraventricular ectopic beats (S).
