Insights

Pediatric cardiologists disagreed with computer interpretations of electrocardiograms more often in children with heart disease. Factors like patient age and computer report complexity influenced disagreement in pediatric cardiology.

Area of Science:

  • Cardiology
  • Medical Informatics
  • Pediatric Health

Background:

  • Computer-assisted interpretation (CAI) aids in analyzing pediatric electrocardiograms (ECGs).
  • Understanding the accuracy and limitations of CAI in pediatric cardiology is crucial for patient care.
  • Discrepancies between human experts and AI can impact diagnostic outcomes.

Purpose of the Study:

  • To determine the frequency of disagreement between pediatric cardiologists and CAI in ECG interpretation.
  • To identify factors associated with disagreement in pediatric ECG analysis.
  • To compare disagreement rates in patients with and without heart disease.

Main Methods:

  • Retrospective analysis of pediatric ECGs from patients with heart disease (HD) and normal hearts.
  • Comparison of interpretations by two pediatric cardiologists (MD1, MD2) against CAI.
  • Statistical analysis to identify factors associated with disagreement, including patient demographics and CAI report complexity.

Main Results:

  • Significant disagreement occurred more frequently in patients with HD (25%) than in normal controls (11%).
  • CAI tended to overinterpret prolonged QT, sinus rhythm with ectopy, and right ventricular hypertrophy.
  • CAI underinterpreted sinus rhythm, sinus arrhythmia, and right bundle branch block.
  • Increased disagreement was linked to HD, younger patient age, complex CAI reports (>3 statements), and cardiologist MD1.

Conclusions:

  • While CAI is a useful tool in pediatric cardiology, significant disagreement with human interpretation exists.
  • Pediatric cardiologists are more likely to disagree with CAI regarding rhythm diagnosis, bundle branch blocks, hypertrophy, and QT intervals.
  • Factors such as heart disease presence and CAI report complexity influence the likelihood of disagreement.

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...

ECG Interpretation of Rhythms

An electrocardiogram (ECG)graphically represents the heart's electrical activity on ECG paper or a monitor.
Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...

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 to...
Pulse rhythm01:30

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 muscle...

Dysrhythmias V: Evaluating Dysrhythmias

Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
