Thank you for your question on HCM!
Regarding your concern, I would explain that your symptoms don't seem to be related to your blood pressure. Your actual blood pressure values seem to be OK.
Your diastolic blood pressure is within the normal ranges too.
Regarding your heart rate
, it doesn't seem to be elevated, becuase it is normal to have similar fluctuations during the day.
Nevertheless, I would recommend performing a Doppler ultrasound
of the cervical arteries to examine the blood flow to the brain and exclude any possible vessel stenosis, which could lead to the episodes of dizziness
Thyroid hormone levels, are necessary to exclude possible thyroid dysfunction
Regarding your headache, I would recommend consulting with a neurologist
for a careful physical examination and a possible brain CT scan to find out the cause. A routine blood tests for chronic anemia or inflammation would be necessary too.
Hope you will find this answer helpful!
