Anyone considering cardiac ablation for AFib should have a thorough workup. An ablation may or may not be successful. If successful, the ablation may last a few months or several years. My 2nd and last ablation was 3 years ago.
As for your immediate need to get relief for your shortness of breath, quite a few of us deal with this symptom. Patience is something you will learn with AFib. AFib changes your life. You will never be the same person again physically. AFib usually is treated with medications and sometimes procedures. Changes in lifestyle are often necessary. However, there is no magic bullet. I wish you the best.
