Hello @jadillow: Changing meds can be stressful and I can understand your concerns. I have taken Atenolol for a number of years along with another blood pressure med called Vasotec. The two work together quite nicely. However, I was concerned about it at first, just like you. I was concerned that my blood pressure might go too low. However, I have settled in quite nicely over the years and feel quite comfortable. I don't have as many spells of a high heart rate nor the "squeezy" feeling in my chest.

I agree with Kanaaz, that you should call your doctor's office with your concerns and ask him/her to explain why the change was made and also express your concerns about your heart rate going too low. Most doctors are more than happy to address your concerns.

Will you post again and let us know how you are doing?
