My son is only 17 and had to have his heart shocked yesterday because of AF. He had pain, shortness of breath and dizziness with bad irregular heartbeat. They aren't sure what caused it but we were sent home after a few hours and now he has to see a specialist on Tuesday. I hope he doesn't have to start medicine at such a young age. He also has anxiety but doesn't take medicine for it. I'm so worried about him although he is doing fine now.
