If you have atrial fibrillation, you may experience heart palpitations. Heart palpitations are an uncomfortable but common occurrence. Most of the time, heart palpitations are not serious. However, if you have an arrhythmia such as atrial fibrillation, you need to see a doctor to get a medical evaluation. With palpitations, you feel like your heart is fluttering, pounding, or racing inside your chest. You might think your heart is adding extra beats or even skipping beats. If you have a rapid heart rate (100 beats a minute or higher), it is referred to as tachycardia. If you have a slow heart rate (less than 60 beats a minute), it's called bradycardia. In addition, if you have heart valve problems, low potassium, or heart disease, or if you have a high risk for heart disease, call your doctor immediately if you have heart palpitations.
