Objective:

To evaluate the performance of vision-enabled large language models (VE-LLMs) in interpreting 12-lead electrocardiograms (ECGs) and compare their diagnostic capabilities with human experts and ECG-specialized models in an exploratory study.

Key Findings:
  • VE-LLMs demonstrated varying performance across different diagnostic categories, with accuracy rates of [insert metrics].
  • Comparison with human experts and ECG-specialized models highlighted differences in interpretation accuracy.
  • The study provided insights into the capabilities and limitations of current VE-LLMs in medical image interpretation.
Interpretation:

The findings suggest that while VE-LLMs show promise in interpreting ECGs, their performance is not uniform and may require further refinement and validation, particularly in clinical settings.

Limitations:
  • The study was conducted on a limited dataset of 70 ECGs.
  • Results may not be generalizable to all clinical settings or patient populations.
  • The retrospective design may introduce biases in data interpretation, including potential biases in model selection.
Conclusion:

The study highlights the potential of VE-LLMs in ECG interpretation while emphasizing the need for rigorous validation and comparison with established diagnostic methods, and calls for future research to explore these models further.
