Ummm..... I think we are mixing up terms here.
I would bet >90% that you are actually experiencing SVT and not atrial fib.
Vagal maneuvers and adenosine do not help atrial fib.
Atrial fib is a problem in the atrium, which adenosine and vagal maneuvers do not affect.
SVT is a problem with the AV node, which vagal meneuvers and adenosine do affect.
The fact that vagal maneuvers make it go away and the cardiologist told you that you don't have to go to the ER every time, makes me think you have SVT.
Marm, if you are giving adenosine for rhythm strip #2, you have serious EMS protocol problems! I am thinking you mistyped. That needs about 20 mg diltiazem IV or defibrillation if seriously hypotensive, not adenosine. Adenosine ain't doing shit except producing a rhythm strip of irregular p-waves at about 190/minute. And IM adenosine is not going to ever work since the halflife of the drug is like 6 seconds, by the way.
Assuming you actually have SVT, you need to see a special kind of cardiologist called an EP specialist (electrophysiologist) who can do a cardiac cath and an ablation to get rid of the aberrent cardiac pathway causing your SVT.
If you actually have paroxysmal atrial fib, which again I doubt, you can be put on calcium channel blockers or betablockers in an effort to help decrease the frequency of attacks. Still see an EP specialist.
If you have specific questions you can PM me.
edit: if you were hospitalized for this, perhaps that time you had atrial fib, but the epsiodes since where you stop them with vagal maneuvers really sound like SVT. Can you elaborate on this?
