I have a racing heart and my dr. Says its anxiety, but its all the time, now my asthma is worse and prednisone, advair  xopenex ventolin dont work. Im on clonozapam which only allows me to sleep 3-4 hours per night and then my racing heart wakes me. Was on thryoid meds last year which caused thryoid storm and had severe heart pounding. My dr. Said it was thryoid storm, the ER doc said it was panic attacks, had several heart tests, lung X-ray all normal, why does it seem that my heart racing and asthma coincide. I started taking 1500 mg of magnesium and 1200 mg calcium to help with the cough spasms . It helps. Im fine during the night and morning with no asthma symptoms, but it starts around 3pm until bedtime. No one seems to have answers for me. They even sent me to a psychiatrist and all he did was double the clonazapam at night so the panic attacks didnt wake me which worked for awhile, now I hardly sleep at all and my heart races constantly but not pounding like when I was in thryoid drugs. Im tired of feeling this way. Ive had a long history of asthma in the past, but no occurrence in about 5 years after having my stomach stapled around my esophogus due to severe reflux which fixed the problem. I know I have allergies. Ever since working outside in the spring, its been bad and cant seem to calm the asthma down.

Hi, Thanks for using Chat Doctor. Racing heart beats may due to cardiac cause, thyroid hormone imbalance or due to hypoxia due to asthma. So get done ECG, echocardiography, thyroid profile, blood sugar level, serum electrolytes, Hologram and spirometry once to diagnose the cause. Keep checking TSH levels once every 6 months. For Asthma, it seems you are not controlled. So get back with the symptoms and your treatment history and Chat Doctor.  If we cure asthma then all other problems will be cured with this if this is the basic problem. Have adequate regular sleep, plenty of fluids, nutritious diet with required calorie and regular outdoor exercises for your wellbeing. Hope I answered your question. Get back with the reports. Consult your doctor for further management. Feel free to ask me if you have any further queries. Wish you good health. Take care. Regards
