Nick,
Often when I give dobutamine for a stress
test, especially in women and younger men, I will get a vagal response—I usually
dread it, because then the test is a complete waste, as there is no way to get
the heart rate up, and I am usually using dobutamine as a last resort. However,
in my anecdotal experience, if dobutamine is given for a stress, and the
patient has a vagal response, I have never seen a positive cath—however, that
has not been correlated in any large scale trials.

Hey Bill,
At what point were they bradycardic? The object of a stress test is to
get the HR up... was it an exercise or drug study?
Did they give you a copy of the 12leads?
Thanks
Nick
