What causes a rapid heart rate? A: According to WebMD, a rapid heart rate, also referred to as heart palpitations, can be caused by a variety of factors, including anxiety, the use of stimulants or caffeine, stress, and hormonal fluctuations during pregnancy.
An abnormally high pulse rate above 100 beats per minute is also called tachycardia, and it occurs when the heart tissues produce electrical signals rapidly, affecting the upper or lower chamber of the heart, or both. Tachycardia, or rapid heart rate, may produce either a regular or an irregular rhythm in the heart.At extremely rapid rates, the heart may not be able to pump oxygen-rich blood efficiently to the rest of the body, and may cause symptoms as well as complications. Emotional factors: Temporary causes of high pulse rate include emotional factors like sudden fear, emotional stress or anxiety, excitement, and nervousness. 2  These are normal responses of the body, and tachycardia may subside after the stimulus is gone.
