I recently had a nuclear stress test (age 61, had light headed feelings one evening), all turned out normal except have RBBB as detected on treadmill part of the test while exercising.  Had slightly elevated blood pressure for first time in my life as well. I have pectus excavatum (funnel chest) not surgically corrected (well they tried in 1953, 4yrs old, but not successful).  I was told "normal" and sent home, but should I be seeing a cardiologist about all this?
HelloThanks for posting at Chat Doctor. I have gone through your description. A nuclear stress test is very sensitive in detecting blockages in the heart. Changes in the ECG during a treadmill test are considered significant. Nuclear stress test also checks the contractility of the heart during the change of rhythm to RBBB. Since you have said that it was reported normal I suppose you had a rate dependent RBBB. So there is nothing to worry about this. If you and a plain stress test I would have suggested you to see a cardiologist. But since this was a nuclear stress test which WPA normal, you need not see a cardiologist now. Wishing you good healthRegards
