Hi, it has been 10 months since my 2nd abalation and was doing great. At the end of November for a week when I stood up my arms and legs started jerking and I was so lightheaded I had to sit down. Then I was in the kitchen feeling fine and I woke up on the floor not having a clue that I had blacked out and fainted. My regular doctor said it was just low blood pressure and nothing to worry about. Could this have anything to do with my afib or palpitations because since then I have had more flipping around in my heart.
