General & Family Physician,  's  Response
Hello,
Thanks for posting in HCM.
Whenever body is put to exertion the heart beats faster to cope with supplying more blood to muscles of body hence its rythm increases.
If you already have history of arrhythmia then increase in heart rate causes heart to erratically send impulse and thus cause heart to go in arrhythmia.
This triggers your symtpoms like chest pain , lightheadedness, tiredness as heart is unable to meet the demand and cause decreased blood supply to brain and lungs.
As you have done your stress test 18 months ago i would advice you to undergo repeat stress test and consult your cardiologist regarding the amount of exercise you can do.
I hope i have answered your query well.
Thank you
