Many possibilities: What do you mean by "unusually fast hr"? Causes of sinus (normal) tachycardia include:fever, pain, anxiety, fatigue, exercise, dehydration, caffeine, asthma inhalers, many other medicines and drugs, hemorrhage, anemia, excess thyroid hormone; then there are abnormal rhythms such as atrial fibrillation or flutter, pat/svt, wpw, and VT - there are many other possibilities.
