In brief: Many causes

Some possible causes of tachycardia (fast heart rate) are abnormal thyroid, anxiety, anemia, fever, drugs or medications, heart disease, abnormal electrical pathways in the heart, imbalance of electrolytes, caffeine, and many other causes.
If this persists, you should be evaluated by your PCP.
