Insights
This study introduces a novel deep learning model using electrocardiogram (ECG) images for rapid COVID-19 diagnosis. The method accurately detects cardiovascular abnormalities associated with COVID-19, aiding pandemic control.
Area of Science:
- Cardiology
- Artificial Intelligence
- Infectious Diseases
Background:
- COVID-19 impacts the cardiovascular system, necessitating improved diagnostic tools beyond RT-PCR and imaging.
- Current diagnostic methods for COVID-19 have limitations in sensitivity and cost.
- Early detection of COVID-19's cardiovascular effects via electrocardiograms (ECG) is crucial.
Purpose of the Study:
- To develop and validate a novel deep Convolutional Neural Network (CNN) model for diagnosing COVID-19 using ECG trace images.
- To assess the model's ability to detect cardiovascular abnormalities linked to COVID-19.
Main Methods:
- A deep CNN model was designed to analyze ECG trace images derived from COVID-19 patients.

Abstract:
Clinical reports show that COVID-19 disease has impacts on the cardiovascular system in addition to the respiratory system. Available COVID-19 diagnostic methods have been shown to have limitations. In addition to current diagnostic methods such as low-sensitivity standard RT-PCR tests and expensive medical imaging devices, the development of alternative methods for the diagnosis of COVID-19 disease would be beneficial for control of the COVID-19 pandemic. Further, it is important to quickly and accurately detect abnormalities caused by COVID-19 on the cardiovascular system via ECG. In this study, the diagnosis of COVID-19 disease is proposed using a novel deep Convolutional Neural Network model by using only ECG trace images created from ECG signals of COVID-19 infected patients based on the abnormalities caused by the COVID-19 virus on the cardiovascular system. An overall classification accuracy of 98.57%, 93.20%, 96.74% and AUC value of 0.9966, 0.9771, 0.9905 is achieved for COVID-19 vs. Normal, COVID-19 vs. Abnormal Heartbeats, COVID-19 vs. Myocardial Infarction binary classification tasks, respectively. In addition, an overall classification accuracy of 86.55% and 83.05% is achieved for COVID-19 vs. Abnormal Heartbeats vs. Myocardial Infarction and Normal vs. COVID-19 vs. Abnormal Heartbeats vs. Myocardial Infarction multi-classification tasks. This study is believed to have great potential to speed up the diagnosis and treatment of COVID-19 patients, saving clinicians time and facilitating the control of the pandemic.

Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
