Could be symptomatic but hemodynamically stable
Adenosine 6mg rapid IV push
follow with 20ccs saline half life very short few seconds)
After 2 minutes 2nd dose 12mg iv push follow with saline
Also try vagal manouver
If adenosine does not work use B blocker calcium channel blocker
Eg Verapamil 5mg over 5 minutes

Verapamil Slow IV push 5mg over 5 minutes

| Patient |
Treatment |
| The patient’s QRS is narrow and rhythm is regular. |
Try vagal maneuvers.
Give adenosine 6 mg rapid IV push.
If patient does not convert, give adenosine 12 mg rapid IV push.
May repeat 12 mg dose of adenosine once. |
| Situation |
Assessment and Actions |
| Patient has significant signs or symptoms of tachycardia AND they are being caused by the arrhythmia. |
The tachycardia is unstable. Immediate cardioversion is indicated. |
| Patient has a pulseless ventricular tachycardia. |
Follow the Pulseless Arrest Algorithm. Deliver unsynchronized high-energy shocks. |
| Patient has polymorphic ventricular tachycardia AND the patient is unstable. |
Treat the rhythm as ventricular fibrillation. Deliver unsynchronized high-energy shocks. |
