Chest Vibrations

There are many posts of people who experience chest vibrations that Cardiologists (or any other doctors) seem to have no answer for. Is there an efficient way to bring the community of sufferers together to compare notes and to try to get the medical community to see this as a real albeit strange problem that shouldn't be dismissed as "anxiety attack"? We all have had the stress tests, halter tests etc and have been pronounced as healthy, but have to live for years with this annoying and sometimes scary occurrence. I would like to hear from those that would like to talk, e-mail , or get together to try to find someone in the medical community who might carry our banner forward. Of course if anyone has "solved" this, we all need to hear about it and spread the word to others.
