I'm sitting in my car and boom, i get flushed, my heart rate is up to 125 bpm, my heart is also pounding in my chest and throat..

Could be something..: Your symptoms could be part of an arrhythmia or some other condition causing your heart to speed up abnormally. These can be picked up by some heart monitors that your primary care provider or a heart doctor could order if deemed appropriate. Many other things can cause this this too, though, including anxiety and panic attacks, so i'd speak with a health care professional first in person!

Go to your MD or ER: Go to your md or er. This is not normal. This could represent a cardiac dysrhthymia (abnormal heart beat), an endocrine problem or physical response to stress. Get it checked out.
