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 LCX
ST elevation in V7, V8, V9, V6
Reciprocal depression in V1, V2
AHA 17-segment model 11, 12, 16
Occlusion severity Total

Which leads should be evaluated?

The catalog marks as primary diagnostic leads V7, V8, V9, V6. ST elevation in V7, V8, V9, V6; reciprocal ST depression in V1, V2.

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 Posterolateral / posterior infarction (distal LCx) identified on the 12-lead ECG?

Distal circumflex occlusion in the left atrioventricular groove. Involves posterolateral and posterior basal walls. 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 V7, V8, V9, V6. ST elevation in V7, V8, V9, V6; reciprocal ST depression in V1, V2. 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 LCX.

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.

How do you open this configuration?
