VENTRICULAR_ESCAPE
Technical documentation
Idioventricular Escape Rhythm
Last-resort ventricular pacemaker firing when higher pacemakers (sinus, atrial, junctional) fail or complete infrahisian AV block prevents their conduction. Wide QRS (≥ 120 ms) at a slow, unstable rate of 20-40 bpm. Ineffective cardiac output, profound hemodynamic compromise, and high risk of progression to asystole.
Also known as: Idioventricular Escape Rhythm · ritmo idioventricular · escape ventricular · ritmo de escape idioventricular · idioventricular escape rhythm · idioventricular rhythm
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 |
|---|---|
| Mechanism | Automatismo |
| Modeled rate | 20–40 bpm (default 30) |
| Regularity | Regular |
| P wave | Absent |
| QRS duration | 180 ms |
| QRS morphology | Wide, ventricular origin |
| AV conduction | No conduction to ventricles |
| Severity | Life-threatening |
Which leads should be evaluated?
The catalog marks as primary diagnostic leads II, V1. Slow wide bizarre ventricular complexes at 20-40 bpm.
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 Idioventricular Escape Rhythm identified on the 12-lead ECG?
Last-resort ventricular pacemaker firing when higher pacemakers (sinus, atrial, junctional) fail or complete infrahisian AV block prevents their conduction. Wide QRS (≥ 120 ms) at a slow, unstable rate of 20-40 bpm. Ineffective cardiac output, profound hemodynamic compromise, and high risk of progression to asystole. 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, V1. Slow wide bizarre ventricular complexes at 20-40 bpm. In the simulator, these channels highlight the correlation with anatomical vectors.
What is the underlying electrophysiological or anatomical mechanism?
It originates from altered conduction in the cardiac conduction system, mediated by automatismo.
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.
