Will a drop in my pulse always be associated with a drop in pressure while taking Concor Cor?

Good morning, from Thursday, he uses Concor Cor 1.25 once a day to lower his pulse, because his average value was above 100 and there were chest pains. Since the use, I have noticed its reduction to 80-95 level (there was no exceedance of 100) and the sensation in the chest has taken a less annoying form (echo of the heart /ecg holter did not show any heart you). At the same time, according to the specificity of the drug/side effects, I was lowered to 100/60. Therefore, I wanted to know if the effect of the pressure reduction will be constant for the whole therapy (I have to finish the entire pack of 28 tablets) or is there a chance of "getting used to the body" and the pressure will return to normal (120/80) while maintaining a reduced pulse? If not, is there any non-invasive way to increase pressure (I do not drink coffee) because at its current level it feels tired, dull and I am not able to work. Thanks in advance for the information.
