high heartrate

Hello ,,I was just checking and seeing if anyone out there has my symptoms and any advice.
When i wake up in the mornings after a nights sleep,,not a nap ,,sometimes my heart starts racing and pounding when i walk around.Also, if I do any kind of activity that early it just pounds out of my chest ,,I do have high bp ,,i take atenolol 50 mg and hctz 25 mg daily ,,,i alos take klonopin .5 , 2 x a day for anxiety...I have noticed this has happened since ive had my son and I had a tubal then i was put on anxiety meds,,but this problem with the heart rate is scary..anyone got any advice?

Atenolol levels do not remain at a constant level throughout the day.  The levels peak and then drop.  This may be why you are experiencing the heart racing symptoms.  Do you take 50mg at once or 25mg twice a day of the Atenolol?  Brand name Tenormin is best as the different generics of Atenolol vary somewhat.  My mom took Atenolol and then the pharmacy switched generics to the Atenolol brand.  This threw her into heart failure and into the hospital.  She had to take the brand name Tenormin and then she felt much better until her heart failure advanced.  Then, she took Toprol XL which is like Tenormin, but stays at a constant level throughout the day.  She felt tired and not so well when she was on the Toprol XL.  She was allergic to the ace inhibitor, which would have helped her heart failure a great deal.
