Sorry to hear that you are having this problem. I had the heart palpations and it turned out to be a heart arythmia due to inflamation of the heart muscle. This is a dangerous condition. It could also be Pleuresy. You need to get a hold of your doctor immediately and get seen for it. I have had both conditions. I hope that you seek help immediately.
