LOTS of reasons: Tachycardia (fast heart beat) can be caused by stress, anemia, infection, fever, dehydration, medication, low blood sugar, hyperthyroidism and many many other causes. Some causes are problems with the heart, others cause your normal to beat too fast. Time to call your doctor and get checked out!
