Technical documentation
Mid lateral infarction (2nd Diagonal Branch / D2)
Occlusion of the second diagonal. Supplies the mid-lateral and low anterolateral wall. Elevation in aVL, V5, and V6.
Also known as: Mid lateral infarction (2nd Diagonal Branch / D2) · segunda diagonal · D2 · infarto lateral medio · SCACEST lateral medio · second diagonal occlusion · mid lateral STEMI · D2 occlusion
What parameters does the model use?
The following values are applied by the simulation engine to this entity. They govern activation kinematics in the 3D model and the real-time synthesis of the 12-lead electrocardiogram.
What parameters does the model use?
| Parameter | Model value |
|---|---|
| Involved artery | LAD |
| ST elevation in | aVL, V5, V6 |
| Reciprocal depression in | III, aVF |
| AHA 17-segment model | 7, 12, 16 |
| Occlusion severity | Total |
Which leads should be evaluated?
The catalog marks as primary diagnostic leads aVL, V5, V6. ST elevation in aVL, V5, V6; reciprocal ST depression in III, aVF.
In the simulator, these leads are highlighted on the 12-channel tracing and corresponding vectors are rendered on the 3D model, displaying electrical changes and anatomical origin simultaneously.
Frequently asked clinical questions
How is Mid lateral infarction (2nd Diagonal Branch / D2) identified on the 12-lead ECG?
Occlusion of the second diagonal. Supplies the mid-lateral and low anterolateral wall. Elevation in aVL, V5, and V6. The characteristic diagnostic waveforms are generated in real time across the simulated 12-lead tracing.
Which leads are critical for diagnostic confirmation?
The primary diagnostic leads are aVL, V5, V6. ST elevation in aVL, V5, V6; reciprocal ST depression in III, aVF. In the simulator, these channels highlight the correlation with anatomical vectors.
What is the underlying electrophysiological or anatomical mechanism?
It represents transmural ischemia secondary to occlusion in the territory of the LAD.
How can this condition be explored in the 3D simulator?
MioAtlas offers direct deep-link reproducibility with preconfigured parameters, allowing full 3D cardiac rotation and lead vector inspection.
