I was a mile from home on foot and I had a full on afib episode, heart felt like it was going about 180bpm. I managed to walk back very slow, kept thinking I was about to pass out, it was a horrible experience. Didn't want to cause a fuss with an ambulance, but I was very close to sitting on nearest bench and calling one. I'm now home and taken my pip and betablocker, luckily it seems to have done the trick. Now feeling completely wiped out!
