I have migraines and near-syncopal episodes with a very short loss of vision bilaterally. These episodes are not orthostatic hypotension because they occur when I am sitting down or lying down, or driving an automobile. I am 62 and female. I get palpitations at night several times a week. I am peri-menipausal.I was hospitalized for three days and no real arrythmias were found on EKG. I am on a month-long Holter montitor. A 24-hour Holter was negative. My 2-D echo showed a pulmonary hypertension, yet I have no objective findings from a pulmonology consultation and exam. I have a cardiologist who will perform a tilt-table test after the Holter Monitor. Carotid artery examination did not reveal response to palpitation of the carotid sinus nor arterial occlusion. CT, MRI and MRA of the brain and brain stem were negative, I take Clonapin several times a week at night, for sleep. I have severe degenerative disc disease on cervical MRI. I am very active physically doing advanced Pilates and cardiowave exercise. I have Baker's cysts bilaterally and a history of a torn calf mucle several years ago. There is a residual clot but Doppler studies are negative for DVT. Thyroid panels are normal. No diabetes. No hypertension. Body weight is normal. Low HDL and very high HDL. Normal cholesterol.I was found to have low potassium and slight dehydration. Potassium suppliments were used in the hospital several weeks ago. Vitamin D was given. I have just returned from Palm Springs when the first attach happened so vit D was not that low plus I was already using a suppliment for vit D.
So what's up with the near-syncope?
