Hi, I am new to this board. I have been having palpitations and PVC"S for a couple of months now. I have never had these problems before. I went to the Dr and he did a EKG but found nothing. He gave me a 24 hour monitor to wear and that's when they found the irregular beats.They called and told me it was not normal and I needed to see my DR and a cardiologist I went to my pcp and he gave me metoprolol. I have been taking it and have cut out caffiene, but I still have it. My heart beats really fast at night when I am laying down. It is not as bad during the day. I went to a cardiologist today, and she did EKG and was not at all concerned. She says it doesn't beat differently at night, but I know it does. I finally got her to reluctantly schedule a ultrasound, but she didn't want to. My question is, could it be MVP and not be heard on seen on EKG? She thinks it is anxiety and panic attacks.Thanks.
