A heart arrhythmia occurs when the heart beats in an irregular pattern. Symptoms of arrhythmias include a fluttering feeling inside the chest, a noticeably slow or fast heartbeat, and chest pain. The condition may be a symptom of another heart condition or may occur as a result of lifestyle factors. Some heart arrhythmias are harmless, while others require treatment. Some can be life-threatening. Treatments include medication, and in some cases, surgery.
