Electrocardiogram01:29

Electrocardiogram

1.6K
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...

Pulse rhythm01:30

Pulse rhythm

721
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...

Area of Science:

  • Biomedical Engineering
  • Cardiology
  • Data Science

Background:

  • Diabetes mellitus (DM) management requires continuous blood glucose level (BGL) monitoring.
  • Traditional BGL monitoring methods are invasive.
  • DM is a significant risk factor for cardiovascular diseases, making ECG analysis relevant.

Purpose of the Study:

  • To propose a non-invasive method for hyperglycemia detection using electrocardiogram (ECG) signals.
  • To analyze ECG signals with discrete wavelet transform (DWT) and machine learning (ML).
  • To explore the relationship between ECG characteristics and blood glucose levels.

Main Methods:

  • ECG signals from 210 individuals (healthy and diabetic) were analyzed.
  • Discrete Wavelet Transform (DWT) was used to extract heart rate (HR) and heart rate variability (HRV) parameters.
  • Support Vector Machine (SVM) and k-nearest neighbors (KNN) classifiers were employed for hyperglycemia detection.

Main Results:

  • DWT-based feature detection achieved 99.8% accuracy for HR and HRV.
  • Moderate correlations were found between glucose levels and HR (0.2985) and HRV (-0.373).
  • Classification accuracy reached 97% for normal glucose and 93% for hyperglycemia detection.

Conclusions:

  • ECG signal analysis, using DWT and ML, offers a promising non-invasive approach for hyperglycemia detection.
  • The findings suggest ECG characteristics can supplement current methods for monitoring blood glucose levels.
  • This non-invasive technique could aid in preventing diabetes-related complications.
