Fairly new on the site and figured I would tell my story as I found help from reading others. In about the month leading up to me going to the doctor and ultimately being told I had AFIB I had felt ectopic beats on and off but almost daily. Being a stubborn young male I never went to the doctor for it and thought they would pass on their own. One Saturday while at home I felt like they were especially prevalent and happening back to back non stop. I ended up going to the local clinic and they did an ekg on me. I knew something was wrong when a look of confusion came over the nurses face and she went to get the doctor. He came in and asked me what was wrong, what drugs I had taken, etc... They showed me my ekg and it was all over the place and very abnormal looking. Throughout this whole ordeal I never felt any of the symptoms of AFIB or even of an irregular heartbeat, I felt just fine through the whole thing. The doctor and nurse suggested I take an ambulance immediately to the hospital as "ekg's like this are not normal in people much less someone my age". I was very hesitant to take an ambulance as I did not feel bad and the hospital was close but took their advice and went. Once I got to the hospital I was sort of a medical mystery. My ekg was still very rough looking and the pulse rate on the screen would jump from 120 to 200 then down to 0 for extended periods of time although i was still very much alive. It got to the point that the nurses stopped coming in to check on me when the rate would go to 0. Still no one knew what was wrong with me. I think they tried some different medication to get my heart rate to come down and normalize but nothing really seemed to work. They did all the normal blood test, urine tests and everything came back normal. This all happened at night so the next day someone came to take an ultrasound of my heart. After that the cardiologist came in and told me I was in AFIB. No one suspected AFIB from the beginning because it is so rare in someone my age. I think the chances are 1 in a couple thousand for a 30 something year old. After diagnosis they started me on an IV of a medicine to get my heart rate to normalize or else they would have to do a cardioversion the next morning. About 4-6 hours after starting that IV drip my pulse normalized. I am now on a daily aspirin as my stroke risk was a 0 on whatever 1-5 scale they use. I have since bought a Kardia mobile device and have not received an AFIB reading since the incident took place. I do get the occasional unclassified reading. I have still felt the occasional ectopic beats also.
As to what cause me to go into AFIB I really have no idea. I was a moderate drinker before hand and slowed that down but still drink 1-2 times a week with no adverse reactions. In fact while drinking I get more normal readings from my Kardia then when I am not. Caffeine does not seem to trigger it either. I have been taking some magnesium and potassium supplements since I had previously had a low Mag level about 4 years ago on a blood test.
I know there are plenty of personal experiences written out there but hopefully someone finds use of this one. I know while I was sitting in the hospital I did some searching on young people with AFIB and could not find many posts.
