If you are worried that the pain in the xyphoid process is related to your heart then I would suggest that this is not the most likely cause of the pain.
Pain in this area could be indigestion
. I suggest you try an over the counter medicine for indigestion. Also, you may have inadvertently bruised the area. Try simple pain killers such as paracetamol
if you are still worried then a visit to your doctor for relevant investigation and reassurance would be my suggestion.
