I've had mild heart palpitations since I started having babies 18 years ago but never like this. For a long time I didn't have them and then suddenly a few months ago I started having them accompanied by chest discomfort, and sometimes even lightheadedness. They only last a few seconds but it is scary and uncomfortable. I had a normal EKG and then my doc ordered an at home monitor for 14 days where she diagnosed me with VT. I was also having ansiety attacks at the time. My doc put me on Metoprolol and the VT had gotten better for a couple weeks but now they're back AGAIN! I wonder if my doc is doing everything she should and there's other testing I should have done. I think she's writing it off as the cause being ansiety but recently I haven't had ansiety and I"m still having these episodes of VT. Any suggestions?? I am a 35 year old female, pretty healty otherwise.
