I've basically has this spontaneous diurnal tachycardia which no one is able to put a cause to at the moment. I've been tried on Bisoprolol 2.5mg for this. And to some effect it is working. Before I was ranging from 90-180 now I'm anywhere between 58-130. However I have noticed my blood pressure has gone up! I never used to have a problem with blood pressure but now it's going up to 144/84. Is this normal with beta blockers? I was under the impression it should be lowering both.
