Hello! Thank you for asking on HCM! Regarding your concern, I would explain that this symptomatology may be related to a seizure. But anxiety and low blood glucose (hypoglycemia) can t be ruled out as other possible causes responsible for this clinical scenario. The slightly elevated blood pressure may have been just a physiological reaction to the event. I recommend consulting with the GP for a careful physical examination, a resting ECG, a chest x ray and some blood lab tests (fasting glucose, complete blood count, thyroid hormone levels, kidney and liver function tests, blood electrolytes,etc.). An EEG is necessary to examine the brain activity to rule in/out the possibility of a seizure. A brain CT scan may be needed in case of abnormal EEG findings. If all the above tests result normal, anxiety would be the most probable diagnosis. Hope to have been helpful! Best wishes, Dr. Iliri
