## 해설

Arrhythmia is an abnormal heart rhythm where the heart beats too fast, too slow, or irregularly. It can occur due to problems with the heart's electrical conduction system. Some types, like atrial fibrillation, can lead to blood clot formation and increase stroke risk. Symptoms may include palpitations, dizziness, shortness of breath, and chest pain.
