The docs normally don't answer a followup question.
It's dangerous to stop Atenolol abruptly. You must taper off slowly.
I suspect that Atenolol is prescribed as a blood pressure pill mainly because it is cheap and effective at reducing BP, but if you are an active young person it is probably a poor choice.
There are at least 50 active BP meds with the most common probably being beta blockers, ace inhibitors, and calcium channel blockers. The beta blockers are also used for rythm problems. Ace inhibitors and ccbs don't normally affect heart rate. A small percentage of people can develop a cough on Ace inhibitors, however.
From personal experience, I would not use a beta blocker unless it was the only way to solve an arrythmia problem. I strongly believe that Beta Blockers are counterproductive to good cardiac health in the long term.
I think that you would be better served to try an Ace inhibitor like AltAce or Zestril, or a CCB like Norvasc. I use a low dose of Altace + Norvasc which has been very successful in lowering my BP.
As far as your high HR goes, I suspect that you are physically out of shape, perhaps overweight, and perhaps have a poor lipid profile. I would suggest walking at least 30 minutes twice per day on a hilly course to condition your cardiovascular system. Don't depend on drugs to lower your HR. Daily exercise is the only long term way to save your life, if you are developing heart disease. If you have a poor lipid profile get on some cholesterol drugs to deal with that.
Good Luck to you.
