Call your GP and make the appointment to discuss your anxiety. They'll have records of your ER visit. Increased heart rate and BP is a common symptom of panic and anxiety. The tests showed nothing physical was wrong. The ER doc was quite aware it was anxiety and was practicing CYA medicine by suggesting the referral. Beta blockers are commonly used to quell the physical effects of panic and anxiety but further medication is worth discussing as well as therapy.
