However, if the fast heart rate becomes severe then palpitations may be observed by the patient. This is an awareness of the heart beating within the chest.

Problems with this electrical conduction system can cause an arrhythmia. Arrhythmias can cause the heart to pump less effectively because the coordination of the heart muscle becomes uncoordinated. Certain arrhythmias increase your risk of other medical problems like stroke or blood clots. In an arrhythmia, abnormal electrical signals through the heart muscle may cause the heart to beat too fast, too slow, or in an irregular manner. In any of these situations, the heart may not be able to pump an adequate amount of blood to the body with each beat.
