"Usually, though, a high heart beat is not due to heart disease, because a wide variety of noncardiac factors can speed the heart rate. These include fever, a low red blood cell count (anemia), an overactive thyroid, or overuse of caffeine or stimulants like some over-the-counter decongestants. The list goes on, and includes anxiety and poor physical conditioning."
