Hi. I Had An EP Study Done Last Year, Everything

Hi. I had an EP study done last year, everything come back fine but the dr said he thought he gave me to much sedatives because I went into a panic attack because they didn't tell me I had to be awake... anyway, my symptoms are getting worse, I have an irregular heart beat, shortness of breath sometimes, I have PACs & PVCS on my EKGs, & a few oher things... my cardiologist says that this isn't any thing to wrry about because it isn't coming from my heart. What about coronary artery disease? Is it possible? I'm 22 years old & my family has a history of heart issues. My grandma has a miral valve prolapse & my granfsther died of a heartattack at 50. & my other grandfather suffered roughly 4 MIs & 5 strokes. My thyroid comes back fine. I just want to know if I should push for another EP study sine I know what is goin on now or what you suggest because I feel like my electrocardiophysiologist doesn't understand what I say...
