Hello,
It depends on the cause. It is worth seeing a good internist or cardiologist to make sure your thyroid is ok, to make sure this is sinus tachycardia rather than another arrhythmia. It is also possible that you have inappropriate sinus tachycardia meaning that your high heart rate is independent of appropriate stimuli. This is a more difficult diagnosis to make and should only be made after other causes are excluded. In the meantime a heart rate of 115 won't hurt you, you just need to see a doctor to help figure out why it is that high. A 24 hour holter will determine your average heart rate over that time period -- this would be helpful to see if it is intermittent or sustained.
I hope this helps. Thanks for posting.
I too had the same phenomenon! My blood pressure was fine until the nurse came in to take it and then up it went. I think they call it "white coat syndrome" meaning anyone in a white coat or even a nurse makes you a bit nervous when your blood pressure is taken. I agree with the previous comment though, if you're concerned get it checked out. It would be worth the peace of mind and I'm speaking from experience. My heartbeat would always race in a doctor's presence or for a medical test. (I have supra-ventricular tachycardia so that didn't help either.) My heartbeat would race up to 180 for no apparent reason but the good news is that I was in sinus so they tell me to take beta-blockers which helps slow it down. Maybe yours is a fluke, especially if you have it in your head that as soon as you sit down at one of those machines, your heartbeat will be high. Have a Happy Easter (:

Remember, some of the symptoms of depression and anxiety is a fast heart rate like with panic attacks. It's a question of which came first. The chicken or the egg?
I was the third case this doctor saw with this effect. Within one week of getting off Paxil, my HR returned to normal.
