Hello,
I can see from your medical history that some of the antiarrhythmic drugs have been tried on you. These bouts of
vomiting and nausea are indeed a side effect of dofetilide.
Therefore, my opinion is also that it should be discontinued. Let me offer you my insight.
A class III antiarrhythmic drug,
amiodarone (Cordarone), is a very effective drug in controlling this
atrial arrhythmia and in preventing further bouts from happening.
If you were my patient, I would consider to put you on that drug, plus associate it with a
beta-blocker, which is helpful in rate control and, also, in preventing from further episodes.
Also, I would recommend you to undergo an
echocardiogram, to assess the structural integrity of the heart valves, also the size of the atrial chambers, in order to further decisions about the strategy of treatment and follow-up.
Hope I have answered your query. Let me know if I can assist you further.
Take care
Regards,
Dr Ivan R. Rommstein, General Surgeon
