A great big donkey!
First, I'd personally NOT go back to the cardiologist, report him to the director of the facility and find a university cardiologist with a brain and better manners. Two, all doctors think women (under age 55) who come in with heart problems are hypochondriacs or neurotic anyway. So you have had anxiety attacks, that does not mean your heart issues don't warrant a look. I'm going through the wierd beating problems too and it is not fun. It does make me edgy/agitated. That does not make you some neurotic little girl who likes to bug doctors for a living. It really angers me when they say things like you're too young or treat you nasty. I went to the ER 3 times in a row with that type of attitude, sent me home with the wrong meds that would have killed me and I had pericarditis (inflammation of heart lining) that could have killed me. Thankfully, I didn't listen and went to a different hospital. I had a female friend die at my age (37) from heart/stroke problems and I have a male friend age 50 with history of axiety attacks that by the time they actually believed him (okay, I yelled at the ER doctors that I would sue) the entire back of his heart was dead and needed 4 stents to open up the front. So it may be unlikely, but it is possible that young women and those with anxiety can have serious heart problems too.
From my reading, your symptoms and results thus far are definitely a cause for futher studies. Have the doctors ordered either a stress test or echocardiogram (ECG)? Honestly, there could be a number of things that could cause these findings and your symptoms, some are serious and some are not. Unfortunately, you cannot tell without taking a good look at the heart. Assuming this could be ventricle tachycardia, I would err on the side of caution as this could become a concern. Can your regular doctor order an ECG? I feel that would be the best route to take. Perhaps explain to the dr. about the donkey cardiologist and show the dr. the test results. I have a feeling he/she may understand your concern and need for futher testing.
If possible, the testing should be done before you go into labor (as complications sometimes arise during labor) and the doctors need to know what they are dealing with. The good news is you have been living with this for a while and it may be a problem but may not be a big problem. The bad news is you don't know either way and an expecting mom should not experience this kind of fear when you are pregnant. No matter what it is, it is in your best interest to find out the cause. As soon as possible, please. You and the baby are in my prayers - Kristin
