Indications
- Stable narrow-complex PSVT
- May consider for unstable narrow-complex reentry tachycardia while preparing for synchronized cardioversion
- Wide-complex regular tachycardia thought to be or previously defined to be reentry SVT
- Does NOT convert atrial fibrillation, atrial flutter or VT
Contraindications
- Known allergy, poison/drug induced tachycardia or second- or third-degree heart block
Precautions
- Side effects include: flushing, chest pain or tightness, brief periods of Asystole or bradycardia, ventricular ectopy
- This drug is less effective in patients taking theophylline or caffeine; reduce dose to 3mg in patients receiving dipyridamole or carbamazepine
- If administered for wide-complex tachycardia/VT, may cause deterioration (including hypotension)
- Transient periods of sinus bradycardia and ventricular ectopy are common after termination of SVT
- Safe and effective in pregnancy
IV Rapid Push
- Place patient in mild reverse Trendelenburg position before administration of drug
- Initial bolus of 6mg given rapidly over 1 – 3 seconds followed by NS bolus of 20mL; then elevate the extremity
- A second dose (12mg) can be given in 1 – 2 minutes if needed
- A third dose (12mg) can be given in 1 – 2 minutes if needed
Injection Technique
- Record rhythm strip during administration
- Drawn up adenosine dose and flush in 2 separate syringes
- Attach both syringes to the IV injection port closer to the patient
- Clamp IV tubing above injection port
- Push IV adenosine as quickly as possible (1 – 3 seconds)
- While maintaining pressure on adenosine plunger, push NS flush as rapidly as possible after adenosine
- Unclamp IV tubing
