The heart's rhythm may be normal or abnormal. Palpitations can be felt in your chest, throat or neck. Palpitations are usually not serious, but they may represent an abnormal heart rhythm (arrhythmia).
Heart palpitations can be caused by many things, such as exercise, anxiety, stress, fear, fever, caffeine, nicotine, overactive thyroid, anemia, some medications and more.

This information may help your doctor figure out both their seriousness and their underlying cause.
