Thanks for answering my post on 10-31-02. I was telling you about my orthostatic hypotension after having 3 ablations for afib with no success. You said you didn't think it was from ablations,and from side effect of meds. I was taken off all my meds for one month to rule out this possibility, and I still had BP problems that are very intermittent. My doctors don't know what really is causing this too happen. Proamatine and florinef have failed to work. One minute I can have normal readings, and the next, it drops drastically when I stand. I never had this problem before my third ablation for my afib. I still have afib even though I am back on flecainide. I just had an episode yesterday while exercising, and was forced to quit. I don't know why BP results are intermittent. Could it be from afib that I can't detect? I was in hospital 4 days with blood pressure jumping all over the place, and passed tilt table test..knew I would, cuz felt good when test was being done. Later that day BP was dropping to low to do stress test. Had stress test in past,and I passed, but I didn't have this problem back then,just Afib. Doc's sent me home with no answers,and said to check with my EP who did my ablations,put on proamatine, then florinef-no luck. I am on coumadin, is it possible that I might have bleeding going on somewhere that could be causing BP problems? My EP is head of Department at Henry Ford in Detroit. He can't locate origination of Afib, or figure out why blood pressure is dropping intermittently. Could I have some kind of blockage? I am 42 and no other health problems.
