In my other response to your question I did not realize that you were in atrial fibrilation. If that is the primary problem, catheter ablation and pacemaker placement has a role in symptom relief, if medical options have been exhausted. This combination of procedurs may help your symptoms, but does not decrease the risk of stroke from atrial fibrillation (only blood thinners do). An evaluation by a cardiac electrophysiologist would be useful to determine if you would benefit from such a procedure.
