A resting heart rate
of 100 or more is not normal And the rate has to go up with exercise - irrespective of cause, even normally. Simple situations like fever and anxiety

We have to to blood tests for haemoglobin

Further work up will be based on the results - exercise ECG, Ambulatory monitoring and so on.
Treatment should be planned on results - at times beta blockers are started empirically.
