Key result
Single culprit artery occlusion significantly increased the rate of automatic ECG misinterpretation compared with multiple culprit artery occlusions (31.3% vs. 12.9%, P=0.045) in patients with STEMI.
Why the study?
The association between culprit artery occlusion and the diagnostic accuracy of automatic ECG interpretation in STEMI patients was unclear.
Does single culprit artery occlusion increase the misinterpretation of automated ECG compared to multiple culprit artery occlusions in adult patients with STEMI?

Automated ECG interpretation misdiagnoses STEMI in over a quarter of cases, with single culprit artery occlusions being significantly more prone to misinterpretation than multiple occlusions.
OBJECTIVE: This study aimed to analyze the association between the culprit artery and the diagnostic accuracy of automatic electrocardiogram (ECG) interpretation in patients with ST-segment elevation myocardial infarction (STEMI). METHODS: This single-centered, retrospective cohort study included adult patients with STEMI who visited the emergency department between January 2017 and December 2020. The primary endpoint was the association between the culprit artery occlusion and the misinterpretation of ECG, evaluated by the chi-square test or Fisher exact test. RESULTS: The rate of misinterpretation of the automated ECG for patients with STEMI was 26.5% (31/117 patients). There was no significant correlation between the ST segment change in the four involved leads (anteroseptal, lateral, inferior, and aVR) and the misinterpretation of ECG (all P > 0.05). Single culprit artery occlusion significantly affected the misinterpretation of ECG compared with multiple culprit artery occlusion (single vs. multiple, 27/86 [31.3%] vs. 4/31 [12.9%], P = 0.045). There was no association between culprit artery and the misinterpretation of ECG (P = 0.132). CONCLUSION: Single culprit artery occlusion might increase misinterpretation of ECG compared with multiple culprit artery occlusions in the automatic interpretation of STEMI.

Kim et al. (2022) conducted a cohort in ST-segment elevation myocardial infarction (STEMI) (n=117). Single culprit artery occlusion vs. Multiple culprit artery occlusions was evaluated on Misinterpretation of automatic ECG (p=0.045). Single culprit artery occlusion significantly increased the rate of automatic ECG misinterpretation compared with multiple culprit artery occlusions (31.3% vs. 12.9%, P=0.045) in patients with STEMI.
