Good question for your cardiologist or EP.

How has your anxiety stress been? Are you reacting to that? Kind of a panic attack feeling. I don't want to imply that but unless you have had a panic attack it can mimic heart issues. I have had one after being released from hospital after being shocked 5 times in 24 hours.

I thought I had another shock as my heart was pounding and my body shaking but my ICD/Pacemaker showed was not having tachacardia or arrymthmia.

What was your diagnosis that you had cardio version done? Is it atrial or ventricle ablation? The heart pounding can be from many medical causes as well as mental after such procedures. It is why you need to discuss with your care givers who probably would like to do some additional test.

Six months from your ablation is quite a long time. Did you have these symptoms after your ablation or is this new. Do you have any symptoms of you had before when they had you do an ablation.

Good to discuss with your doctors we can only give you our experience not medical advice.
