The other day i had about 7-10 seconds of what i believe was Ventricular fibrillation. My heart was quivering and did not pump blood. I have had short flutters before but nothing that frightened me. I read that flutters are normal, but after having my heart do that i am wondering if i should see a doctor. I am a female, 17 yrs old, 110 lbs, and have a family history of strokes/some heart diseases (only older than 40). I have a pretty healthy diet (rarely have caffeine) and i m somewhat active. I want to have reason to believe that it is nothing serious because i am very young, but please let me know if I should see a doctor! Other symptoms: Fatigue lasting several weeks Loss of appetite
