[|Human|] Yesterday I had a fluttering feeling in the left side of my head followed quickly by dizziness and nausea; I almost passed out. When the fluttering sensation subsided I noticed that my vision was blurry. The dizziness and nausea lasted several minutes and the blurred vision lasted several hours. I m 54, male being treated for high cholesteral and blood pressure and I m over-weight. Do I need to see my doctor? Should I be concerned?
[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I understand your concern and would explain that your symptoms could be related to a cardiac arrhythmia. For this reason, I would recommend consulting with your attending physician for a careful physical exam and some tests: - a resting ECG a cardiac ultrasound- a chest X-ray study-complete blood count for anemia-blood electrolytes for possible electrolyte imbalance-thyroid hormone levels to exclude thyroid gland dysfunction. An ambulatory 24-48hours ECG monitoring would help examine your heart rhythm for a prolonged time and exclude possible cardiac arrhythmia. Hope you will find this answer helpful! Kind regards,
