The Crucial Role of Image Quality in AI-enabled ECG Digitization and Interpretation of Occlusion Myocardial Infarction

Link to Publication

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.

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.

Door-to-Balloon Time Outperforms ST-Segment Elevation inPredicting the STEMI vs. NSTEMI Final Diagnosis

In a two-center registry study, investigators compared traditional STEMI/NSTEMI classification with angiographic and interventional diagnoses. Although guideline-defined ST-elevation criteria underpin quality metrics and reperfusion standards, they often fail to capture acute coronary occlusion myocardial infarction (OMI). This discordance has led to proposals for an OMI/Non-OMI paradigm, grounded in pathophysiology rather than ECG morphology. The study examined whether door-to-balloon time < 120 min aligns more closely with final cardiologist adjudication than either ST-segment elevation on ECG or angiographic evidence of TIMI 0–1 flow.

Hyperacute T Waves are specific for Occlusion Myocardial Infarction, even without diagnostic ST elevation

This study aimed to derive and validate a quantitative definition of hyperacute T waves (HATW) by developing the HATW score and evaluating its diagnostic accuracy for identifying acute coronary occlusion in patients with possible ACS but without STEMI criteria.
