buzzing/tremor in chest

When I run or do any other intense cardio exercise, I experience a buzzing/tremor like sensation in my chest right where my heart is.  I have heart palpitations quite often while at rest, and I also have a heart murmur that i'm undergoing tests for with a cardiologist, but i don't usually experience any symptoms while exercising.  This has been happening for approx 2 weeks now.  

I'm 28 female 5'7" and 135lbs.  I eat healthy and exercise.

Any anwers or thoughts are very very very much appreciated.

Have you been able to take your pulse when this is happening?  If so, what has it been?

I wouldn't worry about it.  I started getting that buzzing/tremor under my left breast a few months ago.  I wore a monitor last week and it was doing it.  It wasn't associated with my heart.  Just nerve endings I guess.  My pulse is always normal and slow when I feel the buzzing.  Just tell your doctor.  Mine wasn't concerned.

It was around 135, which is normal for the exercise I was doing.  I notice it most when i inhale.
