Thanks for the welcome! Have not had catecholamines checked that I am aware of? My 1st visit to the specialist (2 1/2 hrs) from my home resulted in my diagnosis & being placed on 50mg atenolol bid as well as .5 klonopine at night in addition to norvasc I was already taking. Blood work was performed & I have yet to hear results? Know part of that was checking for vitamin D deficiency. My heart rate & BP have improved greatly but other symptoms such as stomach pain, chest discomfort, inability to take a full breath & hearing changes seem more prominent. Have always experienced PVC's but with the beta blocker my rhythm abnormalities seem to bother me a little more? Maybe it's just because I have been so accustomed to "skipped" beats & "flutters" with a HR of 90+ instead of 50-60 range it has been holding in fairly consistently? Anyway HUGE relief to have a diagnosis after all of these years. Just a shame I had to do my own research & make the appointment w/the specialist after thousands in med bills
