Technical documentation
Inferior infarction with Right Ventricular extension (proximal RCA)
Proximal occlusion of right coronary artery prior to RV branches and acute marginal. Inferior LV infarction (III > II, aVF) with RV extension (V1, V3R, V4R) and reciprocal depression in I and aVL. High risk of hypotension and AV block.
Also known as: Inferior infarction with Right Ventricular extension (proximal RCA) · coronaria derecha proximal · CD proximal · RCA proximal · infarto inferior con afectacion del ventriculo derecho · infarto de ventriculo derecho · SCACEST inferior y VD · IAM inferior con extension a VD · proximal RCA occlusion · inferior RV STEMI · proximal RCA 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 | RCA |
| ST elevation in | II, III, aVF, V1, V3R, V4R |
| Reciprocal depression in | I, aVL |
| AHA 17-segment model | 4, 10, 15 |
| Occlusion severity | Total |
Which leads should be evaluated?
The catalog marks as primary diagnostic leads II, III, aVF, V1, V3R, V4R. ST elevation in II, III, aVF, V1, V3R, V4R; reciprocal ST depression in I, aVL.
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 Inferior infarction with Right Ventricular extension (proximal RCA) identified on the 12-lead ECG?
Proximal occlusion of right coronary artery prior to RV branches and acute marginal. Inferior LV infarction (III > II, aVF) with RV extension (V1, V3R, V4R) and reciprocal depression in I and aVL. High risk of hypotension and AV block. 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 II, III, aVF, V1, V3R, V4R. ST elevation in II, III, aVF, V1, V3R, V4R; reciprocal ST depression in I, aVL. 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 RCA.
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.
