I take atenolol for tachycardia (as a bonus it has also improved my chronic migraines) I feel fine on it and apart from cold fingers sometimes, have no side effects.
I was helping in a science lesson last week (TA) and the pupils were taking their blood pressure. I decided to take mine too and it was 112/54 and 110/56. Should I be concerned that it is this low? Prior to taking the atenolol I think it was about 110/75.
