If everything looks good with your heart tests, have you checked your blood pressure? Orthostatic hypotension (a drop in pressure when standing) is quite common, and usually not dangerous. Also, dizziness can often be caused by the semicircular canals in the ears. You might want to ask for a referral to an Ear Nose and Throat doctor to check this. Hope you feel better~
Hi
Welcome to the MedHelp forum!
There are many causes of dizziness, lightheadedness, passing out, blackouts etc. It is difficult to comment without examination. I am just enumerating the possible causes. You can discuss this with your doctor and see what has been missed out. Dizziness could be due to postural hypotension (blood pressure falling with change of position), internal ear problems and cervical spondylitis or compression of cervical spinal nerves. All these cause dizziness when you get up from lying down position or when you change position that results in a change in the level of your head. Cervical spondylitis and ear problems also cause dizziness on changing the position of the neck.
Other causes are anemia, claustrophobia, GERD, hypoglycemia or low sugar and some endocrine problems. Endocrine problems, such as an underactive thyroid (called hypothyroidism), overactive thyroid (called hyperthyroidism), adrenal insufficiency (called Addison's disease), low blood sugar levels, and in some cases, diabetes, may lead to hypotension and hence lightheadedness and an off balance feeling.
Certain types of epilepsies and seizures too can cause similar symptoms. If you have an accompanying headache then you must also look at benign intracranial hypertension. Patent foramen ovale and mitral valve prolapsed too could be the cause (commonly known as hole in the heart, probably ruled out in ECHO). It can also be chronic fatigue syndrome if all other causes are ruled out. A brain lesion too can cause dizziness but often there are other neurological signs such as numbness, tingling, loss of function of a limb etc.
Hope this helps. Please let me know if there is any thing else and do keep me posted. Take care!
