VFIB
Technical documentation
Ventricular Fibrillation
Chaotic, uncoordinated electrical activity of ventricular myocardium resulting in zero cardiac output, immediate loss of consciousness, and cardiac arrest. ECG displays irregular, shapeless undulations without identifiable P waves, QRS complexes, or T waves. Requires immediate electrical defibrillation.
Also known as: Ventricular Fibrillation · fibrilacion ventricular · fibrilación ventricular · FV · ventricular fibrillation · VF · V-Fib · vfib
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 | Reentrada |
| Modeled rate | 250–500 bpm (default 320) |
| Regularity | Chaotic |
| P wave | Absent |
| QRS morphology | Chaotic without identifiable complexes |
| AV conduction | No conduction to ventricles |
| Severity | Life-threatening |
Which leads should be evaluated?
The catalog marks as primary diagnostic leads II, V1. Chaotic undulating waveform without identifiable P, QRS, or T waves.
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 Ventricular Fibrillation identified on the 12-lead ECG?
Chaotic, uncoordinated electrical activity of ventricular myocardium resulting in zero cardiac output, immediate loss of consciousness, and cardiac arrest. ECG displays irregular, shapeless undulations without identifiable P waves, QRS complexes, or T waves. Requires immediate electrical defibrillation. 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. Chaotic undulating waveform without identifiable P, QRS, or T waves. 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 reentrada.
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.
