I agree, looks like the tests came back good. Try to stay busy when they hit, and try not to stress to much(easier said than done)
Good luck!
It sounds like you have been thoroughly checked-out and no heart disease was found, that's good, try to remember that when you feel frightened.
If I read your post correctly, your only rhythm symptom is an occasional period of a high HR. Did your doctor(s) describe that as tachycardia or something else? Was PVC or PAC mentioned, or AFib or Flutter?
Again, sounds like you should be just fine, but don't let you BP go up, keep taking your medication...unless you doctor says you don't need it any more.
