Respected user, hi there are many reasons for such symptoms apart from high blood pressure as : - low blood pressure - low blood sugar - high blood sugar - transient ischemic attack - acute bronchospasm - vasovagal shock - severe dehydration - electrolyte imbalances - heat stroke - munchhausen`s syndrome - reactionary to any mental trauma - other underlying pathologies of heart, lungs, brain & much more. So any such episode needs evaluation in terms of etiology & then definate treatment plans are carried out differently for individual patient. Hope this clears your doubt. Thanks for using Health Care Magic & reviewing my answer thoroughly. Wishing your patient happy healthy life. Regards dear take care.
