Diseases and Conditions
Heart palpitations (pal-pih-TAY-shuns) are the feelings of having rapid, fluttering or pounding heart. Heart palpitations can be triggered by stress, exercise, medication or, rarely, a medical condition.
Although heart palpitations can be worrisome, they're usually harmless. In rare cases, heart palpitations can be a symptom of a more serious heart condition, such as an irregular heartbeat (arrhythmia), that may require treatment.
