I had mine on September 12th 2017 and I am still having shortness of breath. I don't know if I have been out of A Fib since about 2 days after it being done. I only think that way because when I take my blood pressure my monitor I use says there is an irregularity. I have not gone back to see my EC since I am suppose to go Oct. 18 th and my nurse said It can do strange things for the first 3 month. Still have the shortness of breath just like before the ablation which is a side effect of the PNI. Feeling pretty depressed. Thanks for your in put.
