Hi, Is Atenolol used for High Blood Pressure and Atrial Fibrillation?? I have been on Atenolol?

Yes, this could be used for both high blood pressure and for helping your A-fib. Atenolol is a beta blocker which lowers blood pressure and it also helps to regulate the heart rate. It lowers the rate of the heart at rest and while exercising. If your heart rate tends to be fast, the Atenolol will help to slow it down. One thing Atenolol cant do is convert your heart back into normal rhythm once atrial fibrillation starts-other drugs are used to do that. It does help improve the heart's efficiency in delivering blood and relieves the symptoms of inadequate flow of blood - dizziness, weakness, and shortness of breath.
A-fib is when the atrium of the heart (one of the top chambers of the heart, the lower ones are ventricles) quivers instead of beating properly because of an electrical problem within the heart conduction. When this happens the blood doesnt circulate properly and the blood can actually begin to clot so when the atrium begins working, a clot can be introduced leading to heart failure or stroke both of which can be fatal. This is why the blood thinners are important. Another important step in the treatment of atrial fibrillation is to uncover and correct conditions (such as hyperthyroidism or use of stimulant drugs) that can cause atrial fibrillation. These steps include:
Stopping the use of stimulant drugs and excessive alcohol intake
Controlling high blood pressure
Correcting hyperthyroidism (too much thyroid hormone) and low blood oxygen levels
Controlling heart failure and treating the diseases of the heart and the lungs that can cause atrial fibrillation
When the heart is in a-fib they must bring the heart back into a normal rhythm. This is called cardioversion. Sometimes meds are given to do this and sometimes electricity is used. Electrical cardioversion is successful in over 95% of patients with atrial fibrillation, but 75% of patients have a recurrence of atrial fibrillation within one to two years. Non-medication treatments of atrial fibrillation include pacemakers, AV node ablation, atrial defibrillators, and the Maze procedure.

I used to be on Atenolol for High blood pressure. I was on it for over 10 years. Six months ago I was diagnosed with Afib and they took me off the Atenolol and started me on Metoprlol and Propafenon. If the doctor wants you to stay on the atenolol and asprin consider yourself lucky. The other meds are HORRIBLE! No energy, weight gain, headaches, depression... the list goes on and on...
