The Crucial Role of Image Quality in AI-enabled ECG Digitization and Interpretation of Occlusion Myocardial Infarction
Overview
The effectiveness of AI-ECG tools depends on the quality of input data—poor ECG image quality can lead to critical misdiagnoses. This case shows how a low-quality scan triggered a false STEMI alert, later corrected with improved digitization. It underscores the importance of ensuring minimally acceptable image quality, as even advanced tools can’t fully correct severe distortions.
Key findings
- A low-quality ECG scan produced a false STEMI alert.
- Improved digitization corrected the interpretation.
- AI-ECG accuracy depends on minimally acceptable image quality.

Highlights
- Acceptable digitization of ECG images requires a minimal quality of input
- Contemporary digitization by the PMcardio digitization software can correct many, but not all, distortions and deletions
- Proportionality between QRS and ST/T is crucial; truncation of any part of the QRS or ST/T distorts these proportions.
