Depends on the cause: Hearts beat fast, generally, for a reason. Do you have fever? Anemia? Infection? Pain? Upset? Bleeding? Stress? Caffeine use? Are you overweight, out of shape, de-conditioned? These and many more reasons may be the cause. Unless your hr is >150, it's likely that the rate is a symptom and not the cause of changes in your health.
