After A Stress Test, Heart Monitor For A Month And

After a stress test, heart monitor for a month and other test that i can not remember the name of. My cardiologist said everything came back normal. That my heart rate increases were from stress. Then he said "I can give you a low dose beta blocker if you want" I told him no I will go see another cardiologist. Is it normal to offer beta blockers to someone that you say their tests are normal?
