What are symptoms of an irregular heartbeat that needs immediate medical attention?

ANSWER

Irregular heartbeat is when your heart beats too slow, too fast, or skips beats. It’s not always a medical emergency. But if you’re short of breath, dizzy, have chest pains, or faint, talk to your doctor right away. These could be signs of serious heart disease.
