IMHO you need to see a cardiologist. My PCP is very good, but he doesn't routinely do EKGs. I've been seeing a cardiologist for years for high blood pressure. My aneurysm showed up unexpectedly and I was shocked because it seemed quite sudden to me. I'm at 4.2 and, of course, concerned, but trying to remain calm and keep my BP down. If I had your symptoms, I'd be requesting a referral to a cardiologist ASAP. Good luck. You're not in this boat alone.
