Common ECG interpretation software mistakes Part II: Computer errors that hide diagnostic clues.

Area of Science:

• Cardiology
• Medical Informatics

Background:

• Electrocardiogram (ECG) interpretation software can produce errors.
• These errors may lead to misdiagnoses and incorrect patient treatments.
• Consistent computer errors can paradoxically conceal vital diagnostic information.

Purpose of the Study:

• To present common and clinically significant peculiarities in ECG computer interpretations.
• To provide methods for verifying or refuting diagnoses suggested by these peculiarities.
• To highlight how software errors can sometimes aid in diagnosis.

Main Methods:

• Collection and analysis of common ECG interpretation software errors.
• Presentation of clinical cases demonstrating these phenomena.
• Inclusion of print illustrations and an online supplement with additional examples.
• Enlargement of original computer interpretations for clarity.

Main Results:

• Identified several common and clinically relevant ECG interpretation software peculiarities.
• Demonstrated how consistent errors can obscure or reveal diagnostic clues.
• Provided practical tools to validate suspected diagnoses based on these findings.

Conclusions:

• Awareness of consistent ECG software errors is crucial for accurate diagnosis.
• Clinicians can leverage specific software peculiarities to uncover missed diagnoses.
• Systematic analysis of computer interpretations, including errors, enhances diagnostic accuracy.
