high heart rate

[kmc2007]

Hi I am 24 years old I for years had my heart rate be 100-114 and recently it's gone up to about 135 and this hasn't been after working out or anything. I don't know if I should be concerned or what and I don't know if I should find a cardiologist and if I would need a referral. I also I don't know if it's just my stress causing it to be high. I just wanting to know what to do and what could happen if it stays high

It is a little high, but like Michelle said, nothing your heart can't tolerate, being a young woman.  I had a tachycardia found by chance (heart rate196, sitting in a doctors office) and started my treatment with my GP.  Most can do an EKG in office, and maybe even hook a 24 or 48 hour holter monitor up to you, and start there. Your heart rate really isn't  a problem, especially if it's a sinus rhythm and is not causing any symptoms.  How do you feel when your resting and your heart rate is 135?  What happens when you do start moving around?

I support Michelle's " advice, as always and jump in only to add a "guy" view.

While a women's HR may be acceptable when higher than the "normal" 60 to 100 at rest, I think a rate at 135 should be discussed with a primary care doctor, best if one who does EKG testing (maybe they all do, mine does).  It may be that you need to take some life-style changes or even some low dose medication such as a beta blocker...which will also lower your blood pressure, you didn't mention your blood pressure or your weight, these are important aspect your doctor will consider.

Good luck and it may be you simply have a higher than "average" HR.

There could be an issue or it could be your normal.  Women, especially small women, generally have higher heart rates.  When you have the 135 rate are you moving around or simply sitting still.  A rate of 135 moving around isn't alarming but if you are just sitting and watching TV then there could possibly be an issue though the rate isn't anything the heart can't tolerate.  It is generally when the heart rte reaches over 200 then it gets concerning.  This said, you may want to go and get a check up with your doctor and especially have your thyroid levels checked.  Hyperthyroidism can cause a higher than normal heart rate.  As well stress and anxiety will also cause an elevated rate.  More than likely you are fine but it really is best to be checked out by a doctor just to be sure.  Take care.
