Hello. Thank you for your question and welcome to HCM. I understand your concern.
The symptoms you described may be with a cardiac origin. Adding the age to the symptomatology, then we should seek for an eventual heart problem. First, I would recommend an EKG and an
echocardiogram. The latter is important, because there may be age-related changes to the heart, especially reflected in the valvular function. Arrhythmias can be produced, which produce the heart racing feeling, and every improper cardiac work and suffering, is transmitted to the lungs, hence the
shortness of breath. Also, a 24-hour heart rhythm monitor or an episode rhythm monitor would be in place, in order to determine what happens with the electrical system of the heart, during the phase where these symptoms arise. It is only after these tests are back, we can further recommend medical treatment or other necessary tests or procedures.
I hope I was helpful. Best regards.
Dr. Meriton
