Thanks for the query to H.C.M. Forum.
Strong heart beats , if you mean palpitation
( very rapid heart beat) than you will have to find out the cause of palpitation.
As far as concerned about the drugs for high blood pressure
, you have not mentioned the reason of high B P.
In my opinion tachycardia( palpitation or strong heart beat) may be due to many reasons as
Anxiety ( tension or stress),Atrial flutter
So please consult a Cardiologist
and get his opinion.
