[Evaluation of electrocardiogram's interpretation in the emergency department]

Area of Science:

• Cardiology
• Emergency Medicine
• Medical Diagnostics

Background:

• Electrocardiograms (ECGs) are crucial in emergency departments (EDs) for diagnosing cardiac conditions.
• Accurate ECG interpretation by emergency physicians is vital for timely and appropriate patient management.
• Variations in interpretation between emergency physicians and cardiologists may affect patient care.

Purpose of the Study:

• To assess the agreement between emergency physicians' and cardiologists' interpretations of ED ECGs.
• To evaluate the clinical impact of any discrepancies in ECG interpretations on patient management.
• To determine the reliability of ECG readings performed by emergency physicians.

Main Methods:

• Prospective data collection of 195 emergency department ECG interpretations from December 1993 to April 1994.
• ECG interpretations were performed by emergency physicians and subsequently by a second, blinded cardiologist.
• Concordance analysis using kappa statistics was conducted to compare interpretations.

Main Results:

• An overall concordance rate of 76% (kappa = 0.41) was found between emergency physicians and cardiologists.
• The concordance rate decreased significantly for abnormal ECGs, with a kappa value of 0.19.
• The study suggests that misinterpretations, though present, had minimal impact on patient management.

Conclusions:

• The quality of ECG interpretation by emergency department physicians is deemed satisfactory.
• Discrepancies in ECG interpretation between emergency physicians and cardiologists are infrequent and generally have limited clinical significance.
• The findings support the current practice of emergency physicians interpreting ECGs in the ED setting.
