Dont worry :)
Just being aware of your heartrate can increase it, 80s-90s is completely normal, especially if you are a bit anxious.
If you get heart rates up to 120s-130s during small anxiety attacks, and 160s-180s during full panic attacks, this is completely normal too.
I would strongly recommend (and I'm afraid I know what I'm talking about here....) that you try not to focus on your heart rate. Getting this on your mind is not a good thing. You have to trust that your heart is completely normal and heart rate variations actually is a good sign.
On a Holter test (24 hours ECG) my heart rate varied from 38 during deep sleep to 180 when I was sprinting to the bus. My cardiologist had one word to describe it: Normal.
The normal rate for a woman is actually 82 and for a man is 72. so you are perfectly normal!
The 80s is well within normal heart rate range. If it was over 100 while you were sitting there getting it checked, that is called tachycardia.
