Correlation between ECG and Cardiac Cycle01:25

Correlation between ECG and Cardiac Cycle

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...
Electrocardiogram01:29

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 the T...

Area of Science:

  • Biomedical Engineering
  • Obstetrics and Gynecology
  • Signal Processing

Background:

  • Cardiotocography (CTG) is vital for fetal well-being assessment during pregnancy and labor.
  • Visual interpretation of CTG has limitations, including observer variability and time consumption.
  • Existing computerized FHR analysis tools are often physician-exclusive.

Purpose of the Study:

  • To develop a user-friendly, LabVIEW-based software for analyzing fetal heart rate (FHR) and uterine contraction (UC) patterns.
  • To improve the objectivity and efficiency of CTG analysis.
  • To create a tool with potential for home-care fetal monitoring.

Main Methods:

  • Utilized signal processing techniques: median filter and peak/valley detection.
  • Developed software based on National Institute of Child Health and Human Development criteria (2008).
  • Validated the software using data from nineteen pregnant women.

Main Results:

  • Achieved 100% accuracy for FHR baseline, baseline variability, early deceleration, UC frequency, and Non-Stress Test (NST).
  • Reached 90% accuracy for acceleration frequency.
  • Attained 95% accuracy for late and variable decelerations.

Conclusions:

  • The developed software provides accurate and reliable analysis of FHR and UC patterns.
  • The system demonstrates significant potential for enhancing fetal monitoring, including home-care applications.
  • Computerized CTG analysis can effectively reduce observer variability and improve diagnostic efficiency.
