Central sharp lower chest pain lasting seconds right at that central boney part. Radiates to jaw and arm and frightening. Norm stress test, EKG and holter. What else causes this?

Muscle spasm. The key here is " lasting a few seconds" the muscles in your chest can have a short lived intense spasm lasting a few seconds. It's more often on the left side of the sternum (breast bone) where the ribs meet. Can you point with one finger where pain is? Anxiety makes it worse. You can also have a short lived spasm of the esophagus that will feel similar.
What other triggers? Tell us more - is the pain exertional? Food intake related? Tender when you press on it? What makes it better or worse?

You are doing the right thing by having a stress test and would certainly do any other cardiac tests recommended. If you believe you are having more severe symptoms or new ones I would seek emergency attention. Read more...
