Sudden increase in heart rate

I had my resting heart rate a week ago increased from 60-65 to 80-85. When I walk with 5-6 lm/h my heart rate jumps to 115. Simple movement could increase it with 10-15 bpm. I am healthy person not overweight and I had a "resting" heart rate on treadmill while walking with1.2 mph and 102 after walking for 3 minutes with 1.7 mph at 10% grade.
Yesterday I had a spike in my heart rate (105 while resting) and went to ER. While they were checking for usual stuff I start feel not well and developed a fever (38.5). Everything seems normal to the doctors there and they send me home with "fever" diagnosis. Today I am better (fever is gone) and my heart rate is down but not as much as I hopped especially under some load.
Is it normal my heart rate to jump several days before I actually get sick and how long I could expect to pass before it returns to normal?
What else could cause a sudden increase in resting heart rate?

I think you already have your answer personally.  When we become ill with a virus or whatever it doesn't happen at that exact moment.  Your system has probably been fighting it off for a few days beforehand and when you spike a temp. it is your bodies natural way of trying to fight off what is wrong or does not belong in your body.  It is pretty normal to have an increase in a heart rate during illness.  Your body is simply just doing its job and the heart just has to work a little harder to fight off what ails you.  Within normal limits a hearet rate is actually anywhere from 70 to 120 altho i personally feel the 120 is a little high it is still considered within the safe zone but i am not the one who set those standards.  Generally speaking it takes about 72 hours for illness to hide in our bodies with colds, flu, etc before our bodies become reactive to it.  I would wait it out until the bug has passed but definately if you feel your heart becomes irregular, you feel dizzy, or have other worrisome symptoms you may have to just hold on but if anything else pops up i would definately call the doc and remember to stay away from any meds that are over the counter that the ingredients end with phrene or phrin....no good and will increase your heart rate.  Hope you feel better soon Zack.

OMG-This is the same thing that is going on with me. I have a normal resting HR of 60. Suddenly my resting rate is 90. I called the doctor she doesnt seem to care becaus it's still normal at less than 100. IMO it doesnt matter that normal is less than 100, normal for me is 60.

I told my good friend, a cardiologist, she doesnt seem to care either.

I plan on going to the doctor next week and asking for an EKG at least. (Doc is on vacation this week).

I am too afraid to work out. I also dont like the "feeling" of this rapidly beating heart, it's very distracting when you are used to a laid back 60 beats.

I do not have a fever.
