Common questions
What does Stable Wide-QRS Tachycardia (ACLS) do?
Use to classify the rhythm (regular monomorphic, irregular/pre-excited, long QT, or unstable) and select adenosine, an antiarrhythmic, magnesium, or synchronized cardioversion accordingly, with early expert consultation.
How is the result calculated?
Branches: regular monomorphic (adenosine 6→12 mg, amiodarone 150 mg / procainamide 20–50 mg/min / sotalol) → irregular/WPW (no AV-nodal blockers, cardiovert) → long QT (magnesium, avoid procainamide/sotalol) → unstable (synchronized cardioversion; polymorphic → defibrillation).
Is this a substitute for clinical judgement?
No. All results are decision-support only, for licensed clinicians. They must be individualized to the whole patient and the latest guideline version.
