I am having a rapid heart rate, shortness of breath, mild dizziness. Sometimes chest pain. I have been to the ER twice. They did a CAT scan, bloodwork and an EKG. Everything was normal. I was sent to a cardiologist who is going to have me wear a heart monitor for thirty days. I feel like this is a long time to suffer my symptoms and am worried it will get really bad in 30 days. Are my symptoms serious enough that I can t wait 30 days?
