Although this can be frightening, it usually isn't serious. Causes Palpitations can be caused by anxiety, lack of sleep, certain medicines, caffeine, or too much heavy exercise. They also may be a sign of heart disease or other diseases.
Care Depends on the cause.
If the palpitations are due to a serious problem, you'll need to have it treated. If a medicine is causing your heart to skip beats or race, your doctor may stop or change the prescription. Otherwise, you will need to stop eating or drinking foods with caffeine in them. You will also need to make sure you get enough rest. If you do not go for treatment, the cause of the palpitations will remain unknown.
