Why does your heart rate change?
Answer All of the above
When the heartbeats too fast, too slow or with a skipping rhythm, a person is said to have an arrhythmia. It is common for children to have extra heartbeats, and many changes in heart rate or rhythm are minor and do not need medical attention if there are no other symptoms or history of heart disease.
