Really odd question here. How come my heart palpitates on cue everytime I bite down the back of my tongue? Vagus nerve?

[braziljjay]

So just accidentally I noticed everytime I contracted or bit down the back of my tongue where it meets my esophagus, my heart would palpitate

like beat fast, irregularly then when I releaseed, it went back to normal.

I'm pretty sure its because the Vagus nerve has something to do with it but not sure.

Any ideas?

What do you mean by "bite down the back" of your tongue? I have no idea what you mean by that.
