Anti-Dysrhythmics Making Atrial Tachycardia Worse?

[MeganMN]

Well, I tried the Norpace and it was a big flop. Not only did it give me daily Inappropriate Sinus Tachycardia, it actually seemed to make my Atrial Tachycardia/SVT worse and more frequent, with longer episodes. I made it a whopping week. My EP seems to be getting frustrated with me and I think Rhythmol is the only med left to try. I have an appointment with another EP to get a second opinion. Has anyone had the experience of the anti-dysrhythmic making your episodes worse?

Norpace ( Disopyramide) is not a frequently prescribed drug in the UK. I've been taking it for a number of years for persistent AF as it is the only drug to have any effect, albeit limited.

I found that Flecainide actually promoted arrhythmias, Afib & A tachy

Propafanone )Rhythmol) was the drug I was on for many years with some success.

[ILowe in reply to BobD]

Flecainide is well known for promoting bad rhythms if you take too much. To mitigate that it is usually taken with a betablocker.

Amiodarone can make the rhythm worse in higher doses.

Hve been on propafenone (Rhythmol) for almost 2 years with good afib suppression results and only very occasional PAC's.
