Technical documentation
Anteroapical infarction (mid LAD, post-D1)
Occlusion in the middle third of the LAD distal to D1. Anteroapical infarction circumscribed to the mid-anterior wall and apex. Prominent ST elevation in V2-V4 with subtle reciprocal changes in inferior leads.
Also known as: Anteroapical infarction (mid LAD, post-D1) · DA media · LAD media · infarto anteroapical · SCACEST anteroapical · mid-LAD occlusion · mid LAD STEMI
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 | V2, V3, V4 |
| Reciprocal depression in | III, aVF |
| AHA 17-segment model | 7, 13, 14, 17 |
| Occlusion severity | Total |
Which leads should be evaluated?
The catalog marks as primary diagnostic leads V2, V3, V4. ST elevation in V2, V3, V4; 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 Anteroapical infarction (mid LAD, post-D1) identified on the 12-lead ECG?
Occlusion in the middle third of the LAD distal to D1. Anteroapical infarction circumscribed to the mid-anterior wall and apex. Prominent ST elevation in V2-V4 with subtle reciprocal changes in inferior leads. 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 V2, V3, V4. ST elevation in V2, V3, V4; 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.
