Insights

A novel deep learning model, CHDdECG, effectively detects congenital heart diseases (CHDs) in children using electrocardiograms. This non-invasive method shows high accuracy, surpassing human experts in early CHD detection.

Area of Science:

  • Pediatric Cardiology
  • Artificial Intelligence in Medicine
  • Biomedical Signal Processing

Background:

  • Early detection of congenital heart diseases (CHDs) is crucial for improving treatment outcomes in pediatric patients.
  • Current detection methods may require invasive procedures or lack cost-effectiveness.
  • Non-invasive, low-cost techniques for pediatric CHD detection are highly desirable.

Purpose of the Study:

  • To develop and validate a deep learning approach, CHDdECG, for automated detection of CHDs using pediatric electrocardiograms (ECGs).
  • To assess the performance of CHDdECG against human expert diagnosis.
  • To explore the contribution of automatically extracted ECG features versus human-defined features in CHD detection.

Main Methods:

  • A deep learning model, CHDdECG, was developed to automatically extract features from pediatric ECGs and wavelet transformations.
  • The model integrated automatically extracted features with key human-concept features.
  • The model was trained on 65,869 cases and validated on multiple real-world and external test sets (totaling over 27,000 cases).

Main Results:

  • CHDdECG achieved a ROC-AUC of 0.915 and specificity of 0.881 on a 12,000-case test set.
  • External validation demonstrated strong performance with overall ROC-AUCs of 0.917 and 0.907, and specificities of 0.937 and 0.907.
  • CHDdECG outperformed cardiologists in CHD detection accuracy, with automated ECG features showing greater importance than human-concept features.

Conclusions:

  • The proposed CHDdECG deep learning model offers a highly effective and non-invasive method for pediatric CHD detection using ECGs.
  • The model's performance surpasses that of human experts, suggesting it can identify patterns beyond human cognitive capabilities.
  • Pediatric ECG analysis with deep learning holds significant potential for advancing CHD diagnosis and improving patient outcomes.

Electrocardiogram Fundamentals

Introduction
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.
Parts of an ECG
An ECG utilizes electrodes on the skin...

Pulse rhythm

Pulse rhythm refers to the pattern of pulsations within specific intervals, offering valuable insights into the regularity or irregularity of the heart's beats as observed through the pattern of pulsation within specific intervals. A regular pulse exhibits a consistent heart rate with uniform waveforms and pulsation force, variations of which can be classified as normal, weak, or bounding.
Conversely, an irregular pulse pattern is termed dysrhythmia, stemming from disruptions in cardiac...

Electrocardiogram

An electrocardiogram (ECG or EKG) is a critical diagnostic tool that records the electrical signals produced by the heart during each heartbeat. This recording is achieved through electrodes placed strategically on the arms, legs, and chest. The electrocardiograph amplifies these signals and produces 12 distinct tracings, offering a comprehensive understanding of the heart's electrical activity.
Three major waveforms are present in a typical ECG recording: the P wave, the QRS complex, and...
