Key result
For predicting myocardial infarction in the interventricular septal area, QV1(+) and qV6(-) showed good sensitivities (79% and 75%) for large infarctions, while QV1V2(+) showed the best specificity (76%).
Why the study?
Do specific 12-lead ECG indicators accurately predict the extent of interventricular septal infarction and proximal LAD culprit lesions in patients with anteroseptal myocardial infarction?
Cross-Sectional (n=115)
Do specific 12-lead ECG indicators accurately predict the extent of interventricular septal infarction and proximal LAD culprit lesions in patients with anteroseptal myocardial infarction?
Specific ECG findings, particularly the absence of qV6, can help identify proximal LAD culprit lesions and extensive interventricular septal infarction in patients with anteroseptal MI.
ECG markers flag extensive septal involvement; extends ECG utility for infarct quantification in anterior MI.

Miyano et al. (2000) conducted a cross-sectional in anteroseptal myocardial infarction (n=115). Electrocardiographic indexes (QV1(+), QV1V2(+), qV6(-)) vs. 201-TlCl myocardial scintigraphy and coronary angiography was evaluated on Diagnostic accuracy (sensitivity and specificity) for predicting myocardial infarction in the interventricular septal area. For predicting myocardial infarction in the interventricular septal area, QV1(+) and qV6(-) showed good sensitivities (79% and 75%) for large infarctions, while QV1V2(+) showed the best specificity (76%).
