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 and can alleviate symptoms like palpitations or shortness of breath. 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 usually receive sedation or anesthesia to ensure comfort. Recovery times vary, but many individuals can return to normal activities within a few days.
