Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that your symptoms seem to be related to a cardiac arrhythmia. Anxiety or a musculo skeletal cause could not be excluded too. I recommend consulting with your GP for a careful physical examination and some tests : - resting ECG and a cardiac ultrasound - chest X ray study - blood lab tests (complete blood count, thyroid hormone levels, blood electrolytes, PCR, sedimentation rate, kidney and liver function tests). An ambulatory 24-48 hour ECG monitoring is necessary to rule in/out possible cardiac arrhythmia. Meanwhile I recommend you to closely monitor your blood pressure and heart rate and refer them to your attending physician. If all the above mentioned tests result normal, the main cause of your symptoms would be just anxiety. Hope to have been helpful! Best wishes! Dr. Iliri
