Beta Blocker

   Hi Dr. I would like to know what are the best source of beta blocker
  (food, fruits, vegetables)? I'm 24 year old with heart Palpitation (130bpm)
  Do exercise, also been told by my cardiologist no heart disease or anything
  to worry. Im on Atenolol on-off. Is it okay to take this medication only when
  you needed the most then stop again ? I dont know if I want to give-up on
  searching and asking my Doctor why this is happening to me (not often) even
  without the Atenolol. I was just hoping it's only anxiety but sometimes if i
  was thinking something like work projects or paperworks it makes me aware
  of my heartbeat again. Pls. give me a feedback and thank you again.

Dear Ron
There are no sources of beta blockers in food. The only way to get a beta blocker is through prescription medications. I do not think it makes sense to take atenolol on and off, as you can have a rebound increase in blood pressure and heart rate when the medicine is suddenly stopped.
I hope this has been useful. I wish you the best of luck. Feel free to write back.
