Summary

Pediatric emergency physicians showed low accuracy in interpreting electrocardiograms (ECGs) compared to pediatric cardiologists. While cardiologists demonstrated excellent reliability, emergency physicians had poor interrater agreement for ECG interpretation.

Area of Science:

  • Pediatric Cardiology
  • Emergency Medicine
  • Diagnostic Accuracy

Background:

  • Electrocardiogram (ECG) interpretation is crucial in pediatric emergency care.
  • Variability in ECG interpretation can impact patient management and outcomes.

Purpose of the Study:

  • To assess the accuracy of ECG interpretation by pediatric emergency physicians against pediatric cardiologists.
  • To evaluate the intrarater and interrater reliability of ECG interpretation among these specialists.

Main Methods:

  • Prospective cohort study involving pediatric emergency physicians and cardiologists.
  • Standardized questionnaires used for ECG interpretation assessment.
  • Analysis of agreement using kappa statistics for abnormality, concern level, and referral need.

Main Results:

  • Pediatric emergency physicians had lower accuracy and interrater reliability (kappa values ranging from 0.24 to 0.63) compared to pediatric cardiologists.
  • Pediatric cardiologists demonstrated excellent intrarater and interrater reliability (kappa values mostly above 0.80).
  • Agreement between emergency physicians and cardiologists was relatively low (kappa values ranging from 0.16 to 0.42).

Conclusions:

  • ECG interpretation by pediatric emergency physicians is relatively inaccurate when compared to pediatric cardiologists.
  • Significant disparities exist in intrarater and interrater agreement between the two groups.
  • Findings highlight the need for improved training or consensus in ECG interpretation for pediatric emergency settings.
