About 3 weeks ago my heart started beating rapidly. After 2 weeks of different doctors, I finally saw a cardiologist who put me on a beta blocker. Palpitations are down but not completely gone. Started to feel light headed yesterday. Have another appointment today with the doctor. Everyone one is saying anxiety. With palpitations for almost a month?! Can some please give me an idea of what can be wrong. I have had 2 ECGs done (both normal) and chest xray is normal too. BP is fine.
