Exploring the Relationship Between Eye Movements and Electrocardiogram Interpretation Accuracy.

Area of Science:

• Medical Imaging
• Human-Computer Interaction
• Physiology

Background:

• Electrocardiogram (ECG) interpretation is crucial for diagnosing cardiac conditions.
• Visual inspection of ECGs is complex, and understanding practitioner perception is key.
• Previous research has not fully explored the link between visual behavior and ECG interpretation accuracy.

Purpose of the Study:

• To investigate how healthcare practitioners visually perceive ECGs.
• To determine if visual behavior, specifically eye movement patterns, correlates with ECG interpretation accuracy.
• To identify differences in visual strategies between correct and incorrect ECG interpretations.

Main Methods:

• 31 healthcare practitioners viewed 11 common ECGs.
• Participant eye movement data were recorded during ECG interpretation.
• Jensen-Shannon distance and permutation tests were used to analyze differences in gaze shift patterns between correct and incorrect interpretation groups.

Main Results:

• Statistically significant differences (α < 0.05) in gaze shifts between ECG leads were found in 5 out of 11 stimuli.
• These differences indicate that visual behavior varies between practitioners with correct and incorrect interpretations.
• Eye movement patterns are a significant factor influencing ECG interpretation accuracy.

Conclusions:

• Visual behavior, particularly gaze shifts between ECG leads, is demonstrably linked to interpretation accuracy.
• Findings provide insights for enhancing both human and automated ECG interpretation methods.
• Understanding visual perception in ECG analysis can lead to improved diagnostic tools and training.
