🔎 Specificity:
- Specificity: 97% specific for OMI when STD maximal in V1-V4
- Of the 99 OMIs detected by STDmaxV1-4, 34% had <1mm STD, and 47 (47%) had accompanying STEMI criteria
- Source: PMID 34775811
- Specificity: 84% specific for posterior OMI when STE in V7-V9 and STD in V1-V3
- Sensitivity: 80% (with respect to diagnostic accuracy of posterior involvement (at least severe hypokinesia on TTE)
- 46 of 87 inferior MIs with posterior leads had posterior ST elevation of at least 0.5 mm in 2 consecutive leads of V7-V9
- Significant STD in V1-V3 was noted in 52 patients (60%)
