[|Human|] I felt a mild pain and flutter with simultaneous feeling of lightheadedness earlier today. Only lasted a few seconds but I thought I was going to feint. Then felt a warm feeling on the back of my neck and up the back of my head. What might cause this?
[|AI|]  Hello, Your symptoms could be related to possible cardiac arrhythmia or low blood pressure values. I would recommend consulting with your attending physician and performing some tests:- A resting ECG and a cardiac ultrasound.- Complete Blood Count for anemia.- Blood electrolytes for any possible imbalance.- Thyroid hormone levels for possible thyroid gland dysfunction.- An ambulatory 24 to 48 hours ECG monitoring to investigate for any possible cardiac arrhythmia. You should discuss with your doctor about the above tests. Hope I have answered your query. Let me know if I can assist you further.
