I'm on Propranolol for SVT and high blood pressure..I have only seen a small difference..so small, not even sure is I have any improvement..I was wondering how long it takes to work..should it work with the first pill or does it take awhile?

I would give it 2 weeks. You should notice a change in your blood pressure by then. I'm on the same - Inderal LA 60mg but still having the headaches - so they will most likely increase it or change the drug. I noticed immediate blood pressure changes but consistently changed after about 2 weeks.

Be aware: Betas will definitely make you tired!!

I've noticed chest pain..do they cause that?

Not that I know of. If you're having chest pain, definitely call your doctor asap. It could be something else!
