Heart Palpitations - American Family Physician
Heartbeats that are hard and fast are called palpitations (say pal-pit-ay-shuns). Your heart is like a pump. Each time it beats, it pumps blood through your body. When you exercise, it is normal to hear or feel your heart "pounding" as it beats faster. But if you have palpitations, you might feel your heart beating fast while you are sitting still or moving slowly. Learn more here.
