Hello! Thank you for asking on HCM! Regarding your concern, I would recommend you to perform a cardiac check up to rule out any structural or rhythm disorders. A resting ECG, cardiac ultrasound and an ambulatory ECG monitoring are helpful to that issue. It seems to be just stress, that produces those symptoms and your heart racing, nevertheless we have to be cautious. I would not encourage you to continue using that blue inhaler, but to try to address the factors responsible for your clinical scenario. Some blood tests would be necessary to exclude some systemic disorders (anemia, thyroid dysfunction, renal disorders, etc). Hope to have been helpful to you. Greetings! Dr. Iliri
