Beta blockers like atenolol do slow the heart rate so your rates in the 50's at rest & even lower when asleep aren't unusual. Does your heart rate increase appropriately when you're physically active? I wouldn't recommend heart rates below 50 when up and about as symptoms of fatigue, lightheadedness, low blood pressure & shortness of breath with exertion can occur.

A heart rate of 48-56 bpm suggests that your hyperthyoidism is probably adequately controlled on methimazole alone. You should discuss this further with your doctor regarding reassessment of thyroid function while you are on this regimen and also to help determine whether you can be managed with one OR the other medication alone and also reassess the diagnosis. Good luck.

Was taking 25mg Athenolol for HBP along with avapro 300mg. Started cutting my atenolol dose in half as my resting heart rate hovers around 59-60. The 25mg pills are hard to cut properly and so i sometimes take an uneven dose. Can this cause issues?
