SVT
Also testable as: Supraventricular tachycardia
Etiology / Pathophysiology
- Reentry rhythm above the ventricles.
- Very fast rate reduces filling time and can reduce cardiac output.
Medications
| Class | Why it matters |
|---|---|
| Antiarrhythmics | Adenosine may be used for stable narrow-complex SVT per protocol. |
Nursing actions
- Assess stability: blood pressure, chest pain, mental status, perfusion.
- Prepare vagal maneuvers or adenosine for stable clients per protocol.
- Prepare synchronized cardioversion if unstable per emergency protocol.
Complications
- Hypotension
- Syncope
- Heart failure
- Ischemia
NCLEX cues
- Narrow fast regular rhythm.
- Unstable tachycardia needs synchronized cardioversion.
Memory hooks
- Fast and narrow: check stability first.
Labs / Diagnostics
- Trend assessment findings and ordered diagnostics; verify exact values with school source material.
Review notes
- Session-derived study seed. Verify against school materials, ATI/NCLEX review sources, current orders, and facility policy before relying on details.
