Electrocardiogram

8.7K
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...

Electrodes: Overview

3.1K
 Electrochemical measurements are conducted in an electrochemical cell composed of various components that control and measure the current and potential. One fundamental component is electrodes, conductive materials that enable electron transfer reactions at their surfaces.
There are two main types of electrodes in electrochemical cells. The first type, known as the working or indicator electrode, has a potential that is sensitive to the analyte's concentration and reacts to changes in...

Area of Science:

  • Biomedical Engineering
  • Obstetrics and Gynecology
  • Medical Informatics

Background:

  • External electrohysterogram (EHG) recordings offer insights into uterine electrical activity during contractions.
  • Understanding labor mechanisms is crucial for preventing preterm birth, a leading cause of neonatal mortality and morbidity.
  • Previous promising results highlight the potential of EHG in labor prediction and obstetric applications.

Purpose of the Study:

  • To present a comprehensive database of multi-electrode EHG recordings for research.
  • To facilitate independent analysis and development of new technologies for obstetric care.
  • To support advancements in understanding uterine function and labor.

Main Methods:

  • Compiled a database of 122 4x4 electrode EHG recordings from 45 pregnant women.
  • Utilized a standardized recording protocol and electrode placement system.
  • Included simultaneously recorded tocographs, event annotations, and obstetric data.

Main Results:

  • The database contains recordings from the third trimester (112) and during labor (10).
  • 32 participants contributed 2-7 repeated recordings during the same pregnancy.
  • Data collected in Iceland between 2008-2010.

Conclusions:

  • The published EHG database enables novel, independent research.
  • Facilitates the development of advanced diagnostic and predictive tools for obstetric care.
  • Aims to contribute to the creation of life-saving technologies for newborns.
