I am on water pill and atenolol for high blood pressure. In the mornings my blood pressure is around 85/60 with heart rate 57. Is this too low?

Yes. That blood pressure is too low. It does not seem like you have any reason to keep the BP that low. Even if you are not experiencing any symptoms due to that low BP, it does not leave much "buffer" room. I think your medications need to be adjusted to allow for higher blood pressure. Please see your doctor as soon as possible.
Possibly. If you are experiencing lightheadedness or dizziness then your blood pressure is too low, otherwise contact your health provider to see if you need to cut down on your medicine.
