Hello! Thank you for asking on HCM! I carefully read your question and would explain that your symptoms don t seem to be cardiac related. I would like to know your blood pressure and heart rate values lately. You should know that a metabolic disorder like thyroid dysfunction or chronic anemia could be the cause of your symptomatology. A high blood pressure could also cause this symptoms. As the ringing in your ears is bilateral, I would exclude any possible intracranial cause (like possible vessel malformation etc.). So I would recommend you to closely monitor your blood pressure and heart rate and refer those values to your attending physician. It is important performing some tests : -complete blood count -thyroid hormone levels -blood electrolytes -PCR, sedimentation rate -kidney and liver function tests. You should discuss with your doctor on the above issues. Hope to have been helpful! Best wishes! Dr. Iliri
