ASYSTOLE
Technical documentation
Ventricular Asystole
Total absence of electrical and mechanical ventricular activity ('flatline'). No cardiac output, no pulse, no blood pressure: clinical cardiac arrest. May present occasional isolated P waves ('ventricular standstill'). Requires immediate CPR and epinephrine; electrical defibrillation is ineffective and contraindicated.
Also known as: Ventricular Asystole · asistolia · asystole · parada cardiaca asistolia · linea plana · ritmo no desfibrilable · cardiac arrest asystole
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 | Bloqueo |
| Impulse origin | Sinoatrial node (SA node) |
| Modeled rate | 0 bpm |
| Regularity | Regular |
| P wave | Absent |
| QRS morphology | No electrical activity |
| AV conduction | No conduction to ventricles |
| Severity | Life-threatening |
Which leads should be evaluated?
The catalog marks as primary diagnostic leads II, V1. Flatline absence of electrical activity: verify in at least two orthogonal leads.
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 Asystole identified on the 12-lead ECG?
Total absence of electrical and mechanical ventricular activity ('flatline'). No cardiac output, no pulse, no blood pressure: clinical cardiac arrest. May present occasional isolated P waves ('ventricular standstill'). Requires immediate CPR and epinephrine; electrical defibrillation is ineffective and contraindicated. 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. Flatline absence of electrical activity: verify in at least two orthogonal leads. 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 SA_NODE, mediated by bloqueo.
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?
