I m glad your seeing your doctor for this complaint. When a patient feels their heart is skipping, beat too fast, too slow, or any other weird feeling related to their heart s beat that they can notice - we call them palpitations. Most of the time these are totally harmless but do not cancel your appointment. Tell your doctor everything about your symptoms. He or she might send you to have what is called an EKG or electrocardiogram. They place harmless stickers on your chest, arms, and legs for a few minutes while they record your heart s rhythm. Best of luck to you.
