a feeling of heart skipping beats in upper part of stomache

There is another possible cause for the heartbeat at the top of your stomach area, and you should check it out because it's potentially life-threatening. I also have palpitations (STV's) and can feel them in the area right below my breastbone. This where the aorta is located, and what I am feeling is the beat in that large blood vessel. I have had this for years, so in my case it is not anything to worry about, but if this is new for you, it could mean that you are developing an aortal aneurysm. This is a swelling in an area of the aorta, which can rupture if it gets too large. The test is an ultrasound, which is painless and not invasive. Please get it checked out.

Mine turned out ot be too much aspartame which also can cause many other symptoms. From all the sugar free drinks and foods i was having. So much for trying to be healthy! they quit within just a few days after cutting out aspartame, although its said it takes 60days to get it completely out of your system.
