I too suddenly found myself having vibrations in my chest. Not knowing what was happening I got up and went to the ER. They didn't find anything (it seemed to go away if I got up and walked around). I did this twice and then one of the Dr.s prescribed Pantoprazol to see if it would help. (Another sign that I didn't pay much attention to was the burping. A fair bit more than I was used to.) Anyway, over the next couple of weeks the symptoms diminished until some nights I had no vibrations. (You had to sleep on your back.) When I ran out of the Pantoprazol I didn't immediately renew the prescription. Within a few days the vibrations came back. I renewed and they diminished again. I've started to do leg lifts while lying down to start to strengthen my stomach muscles. That also may be helping. And losing some weight. Anyway, I'm good now. Wish you luck.
