Cardiac ablation is a medical procedure used to treat certain heart rhythm disorders, known as arrhythmias. During the procedure, a doctor uses heat or cold energy to destroy small areas of heart tissue that are causing abnormal electrical signals. This helps restore a normal heart rhythm. The procedure is typically performed in a hospital setting and may involve the use of catheters, which are thin, flexible tubes inserted into blood vessels. Patients may experience improved symptoms, such as reduced palpitations or fatigue, and the recovery time can vary depending on individual health factors.
