WPW_SINUS
Technical documentation
Wolff-Parkinson-White (Sinus Rhythm)
Congenital presence of an anomalous muscular accessory pathway (Kent bundle) connecting atrium and ventricle, bypassing the AV node delay. Impulse travels faster through the pathway, preexciting ventricular myocardium: short PR interval (< 120 ms), initial slurring of QRS (delta wave), and widened QRS with secondary repolarization changes.
Also known as: Wolff-Parkinson-White (Sinus Rhythm) · Wolff-Parkinson-White · WPW · sindrome de Wolff-Parkinson-White · Wolff-Parkinson-White en ritmo sinusal · preexcitacion · onda delta · via accesoria · haz de Kent · WPW pattern · Wolff Parkinson White
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 | Preexcitación |
| Impulse origin | Sinoatrial node (SA node) |
| Modeled rate | 60–100 bpm (default 75) |
| Regularity | Regular |
| P wave | Sinus (upright in I, II, aVF) |
| PR interval | 80–110 ms (default 95) |
| QRS duration | 130 ms |
| QRS morphology | With delta wave (preexcitation) |
| AV conduction | 1:1 AV conduction |
| Severity | Clinically significant |
Which leads should be evaluated?
The catalog marks as primary diagnostic leads V1, V2, II, III, aVF, I, aVL. Short PR interval (< 120 ms) and delta wave; vector polarity localizes accessory pathway.
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 Wolff-Parkinson-White (Sinus Rhythm) identified on the 12-lead ECG?
Congenital presence of an anomalous muscular accessory pathway (Kent bundle) connecting atrium and ventricle, bypassing the AV node delay. Impulse travels faster through the pathway, preexciting ventricular myocardium: short PR interval (< 120 ms), initial slurring of QRS (delta wave), and widened QRS with secondary repolarization changes. 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 V1, V2, II, III, aVF, I, aVL. Short PR interval (< 120 ms) and delta wave; vector polarity localizes accessory pathway. 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 preexcitación.
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.
