Hello! Thank you for asking on HCM! I understand your concern, and would like to explain that your symptoms may be related to different disorders: - cardiac related (like a supra-ventricular paroxysmal tachycardia) - a metabolic disorder (like a thyroid hormone dysfunction or adrenal gland dysfunction) - a blood electrolyte imbalance - anxiety I recommend consulting with your GP for a careful physical examination and some lab tests (complete blood count, thyroid hormone levels, blood sugar, blood electrolytes, kidney and liver function tests, urinary metanephrines, etc.), to find out the possible cause. An ambulatory 24 hours ECG monitoring and a cardiac ultrasound should be performed to establish the diagnosis of cardiac arrhythmia. Hope to have been of help! Best wishes, Dr. Iliri
