Hello and thanks for the query
I have read your mail in detail. You are taking beta-blocker
which is a good drug for PSVT
. It reduced Blood pressure by reducing Heart Rate
. The figure you have written is very much unlike by such a small dose. It might be a machine error.
But if your are feeling any symptoms like vertigo
etc. than immediately stop the medication and consult your doctor again.
PSVT is not a life threatening unless you have other heart related issue. It can be suppressed by inducing vomit, pressing your eyes with your hands (not others) and by dipping your head into water.
So just relax and check your BP and Heart rate manually and consult your doctor. Change in medication may help you.
