gram0322, Would be difficult and not appropriate to tell you what to do when you are being treated by a EP. That are experts in this field.

It sound like your AFIB causes may not be what the Multag medication is used for. A lot of rhythm drugs have side affects like conduction delays and changes to t-waves, etc. EP can see all this on holter monitors and thus his/her advise to stop.

I would speak to your EP and express your concerns and get more information on why told to stop, it's reaction on your condition, etc. If you are still concerned would get a second opinion.

Ablation does have risks but can fix a lot of issues with AFIB and VFIB. I had one done on right ventricle that stopped the PVCs coming from that area. I still have PVCs from 3 different areas in LV but EP wants to try medication first. I am on a low dose medication for this.

Do you have a AICD/Pacemaker? You stated you have be controverted 4 times this year. Was this done in office or was it a AICD. Your heart rate is very low. Mine was very low and can have impact on your heart being able to have normal rhythm. I have pacemaker to keep in at normal ranges.
