Fast Heart rate, but low blood pressure -What do I do?

Hello,

I have a fast heart rate but low blood pressure and my cardio wanted to put me on a very low dose of beta blockers. I am borderline hypothyroid and my cardio said my heart is fine, it's my thyroid giving me the fast heart rate.

So, my question is: How do I take a beta blocker when my blood pressure is already low? Its always 90/60. Btw, my heart rate is only fast when I'm anxious (like at the dr's office where it spikes to 130) but my resting heart rate is consistently in the 70s-80s based on a holter and months of me documenting my bp and heart rate at home with a bp cuff. Once my cardio saw that, he told me use of the beta blockers is up to me.

Any suggestions?

Beta blockers are commonly used to treat symptomatic hyperthyroidism. They can slow the heart rate down with only having some marginal effects on blood pressure (although it will lower it some). However, if you are having a lot of symptoms from excessive thyroid activity, you might consider seeking further opinion/evaluation from an endocrinologist -- who might suggest other medications/treatments to control an overactive thyroid (as well as making sure there are not other issues that should be addressed, ie. the cause of your hyperthyroid).
