Hello, I am a 19 year old female. I have been fainting off and on for almost 5 years. Now it occurs at least 3 times a week, and I'm scared to drive or do anything. My ECG revealed right atrial enlargement, incomplete right bundle branch block, rare premature ventricular and rare premature atrial contractions, and said abnormal ECG. I haven't seen anyone here use the word rare. Why are they rare? I've also experienced these symptoms, but I just thought it was stress. I have an appointment with a cardiologist in a month, can anyone explain to me what's wrong with me?
