If she has sustained rate over 100 bpm, then something is going on. She should be seen by a doctor. Perhaps she's sick with something and doesn't realize it.
To me that pulse rate seems really high. I think that she is Tachycardic I would seek medical advice ASAP as this can lead to a Myocardial Infarction (heart attack) if left untreated. Her blood pressure however is normal. Please DO NOT take this over medical advice as I am only a student.
