Thanks for writing in.
A high pulse rate can be either due to simply anxiety
or due to a heart condition as well. If you want to be absolutely sure that this works for you, I would suggest the following:
a. Drink plenty of water, atleast 3-4 litres in a day
b. Try yoga
and deep breathing to take care of any possible anxiety
c. Consult a physician and get an electrocardiogram done. This should rule out any major disturbances.
However, I would seriously recommend that you use your skills to find another "job".
Hope this helps.
