<s>[INST] Been having heart palps for 2 years now.  Seen cardioligist.  Blood work, electrocardiogram,  24 hour monitor,  48 hour monitor,  Stress test non dye.  Said my heart is fine.  I have been having i guess a pressure build up in my left shoulder then i feel palps it really doesnt feel right.  What should i do now? [/INST] hi, I feel your body check up related to heart is almost completely done. but then also if palpitations are persistent, then get an ecg done during those palpitations and show to a cardiologist. if that's normal, then I feel you should not worry much. </s>
