Had an ablation 3 months ago. Have been much better since and have had only 4 episodes of AF in that time with lots of ectopics just after the ablation to almost none now. This evening however I have had 4 episodes of feeling very strange and heart rate starts to climb ( only from 53 to approx.77 ) and I feel very odd just like the start of AF, when in my case the body seems to go into shock, and then after only 2 or 3 minutes all goes back to normal. Can AF kick in for such a short time or could it be something else ? Has anybody had similar ?
