Hello and thank you for using HCM. I carefully read your question and i totally understand your concern. I will try to explain you something and give you some advises.
Chest pains and palpitations might be different problems and all sow they might be related with each other. Let me explain this.
Someone might experience palpitations for different reasons. It might be a
sinus tachycardia, extra-systolic beats, or other rhythm problems like paroxysmal supra-ventrikular arytmias, atrial
fibrillation. This rhythm problem might happend from diferet reasons from simple emotional stress to other pathologyes like anemia,
hyperthyroidism or
ischemic heart disease. This is the point when palpitations are related with chest pain. If the heart experience ischemic problems, manifested with chest pains, this heart suffering with
ischemia leads to rhythm problems.
Ischemic chest pains have some characteristics. They are retrosternal chest pains, like squeezing, heaviness, tightness. They are exacerbated by effort and prolong from 10 to 30 minutes.
If you tell me that you experience chest pain with palpitations it might be an ischemic problem or not. Sometimes just an innocent sinus tachycardia might give you this
chest discomfort which is not related with ischemia.
The fact that you all ready did a
stress test and was normal is a good thing, but the stress test is not allays 100 % sensitive for ischemic problems.
So,if I was your treating doctor I would recommend you again a cardiac examination and maybe an holter monitoring for this palpitations.
Hope I was helpful. Best regards
