Answer 1

Answer:

When the heart beats too fast, too slow, or with a skipping (irregular) rhythm, a person is said to have an arrhythmia. A change in the heart's rhythm may feel like an extra-strong heartbeat (palpitation) or a fluttering in your chest. Premature ventricular contractions (PVCs) often cause this feeling.

Your heart normally beats in a regular rhythm and rate that is just right for the work your body is doing at any moment. The usual resting heart rate for adults is between 60 to 100 beats per minute. Children have naturally higher normal heart rates than adults.
