I've been told I have an irregular heartbeat. What does that mean?

An irregular heartbeat is a condition in which the heart beats at an abnormal rate or rhythm. This can be caused by a variety of factors, such as stress, caffeine, and certain medications. It's important to see your doctor if you experience any symptoms of an irregular heartbeat, such as chest pain, dizziness, shortness of breath, palpitations, or fainting.
