<human>: I had an episode at work where I was standing at the register and I blacked out but did not fall to the ground but when I came to I was resting my head on my hand and my body was shaking and so were my legs. I went to the ER but they did not find anything. Just wondering what might have caused it. To me it seemed like a mini seizure but not sure.
<bot>: Hello! Welcome on Chat Doctor ! Your symptoms could be related to different possible disorders: orthostatic hypotension, a seizure, low blood pressure, a cardiac arrhythmia, hypoglycemia, an electrolyte imbalance, etc. For this reason, I recommend you to measure frequently your blood pressure values in the next days in sitting and standing up position. I would also recommend performing some tests: - a complete blood count-fasting glucose - a resting ECG and cardiac ultrasound- an ECG Holder monitoring for cardiac arrhythmia- a Head Up Tilt test for orthostatic hypotension- an EEG. You should discuss with your doctor on the above tests. Hope to have been helpful to you! Kind regards,
