Correlation between ECG and Cardiac Cycle01:25

Correlation between ECG and Cardiac Cycle

8.4K
The electrical signals recorded on an electrocardiogram (ECG) occur before the mechanical processes of contraction and relaxation during the 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

3.2K
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...

Area of Science:

  • Cardiology
  • Medical Informatics
  • Artificial Intelligence in Medicine

Background:

  • Heart Rate Variability (HRV) is a known indicator of diabetic complications.
  • Early detection of diabetes is crucial for managing its progression and preventing severe health outcomes.
  • Electrocardiogram (EKG) signals contain valuable information for cardiovascular health assessment.

Purpose of the Study:

  • To design and validate a Convolutional Neural Network (CNN) model, RNC-Rica, for diabetes diagnosis using EKG recordings.
  • To integrate entropy metrics with CNN architecture for improved diagnostic accuracy and model stability.
  • To assess the model's capability for early detection of diabetes, including subclinical stages.

Main Methods:

  • Development of a CNN architecture (RNC-Rica) for two-dimensional convolution-based feature extraction from EKG signals.
  • Simultaneous analysis of EKG features, age, HRV measures, and entropy measures within the model.
  • Evaluation of five different test setups by integrating combinations of convolutional layers and entropy metrics.

Main Results:

  • The RNC-Rica model achieved an accuracy of 70.3%, sensitivity of 78.4%, specificity of 62.0%, positive predictive value of 68.0%, and an F1-Score of 72.8% (Test 4).
  • Entropy metrics demonstrated an improvement in the model's stability.
  • The model showed capability for early detection in subclinical stages of diabetes.

Conclusions:

  • The regularized nearest centroid-Rica model augmented with entropy metrics is an effective tool for early diabetes diagnosis via EKG.
  • The model exhibits high sensitivity and statistical significance for clinical classification of diabetes.
  • This approach offers a promising non-invasive method for identifying diabetes at its earliest stages.
