Started in Nov and ruled out vision with eye doc, ruled out sinus infection, so then to general doc, referred to cardiologist. Ended up at
Mayo Clinic in MN for 2 weeks of testing. Cardiac exams and tests all normal: included 24 hour BP monitor, 24 hr holter monitor EKG, standard EKG, both treadmill stress plus dobutamine stress test and two echocardiograms - all normal.
