A member asked:

Is a resting heartrate over 100 normal? it hardly ever goes down

Maybe, : "normal" heart rate is 60 to 100. But may also indicate dehydration, anemia, infection, pain, drug effect, endocrine abnormality (high thyroid, low blood sugar, high adrenaline), or deconditioning. A general history and physical exam should reveal clues to almost all of these.

Many possibilities..: For a 27 y/o female, a resting hr of >100 is unusual. Many possibilities, most are benign. It probably does go down during sleep... May be you're checking only at times when you are anxious, or you are deconditioned (out of shape). I'd suggest regular daily, aerobic exercise, and if still fast after 3 or 4 weeks, then see a doctor. A 24 hour holter monitor would be appropriate as an initial step.
