Atrial flutter

Atrial flutter is a type of abnormal heart rhythm that originates from the upper chambers of the heart, called the atria. It is characterized by a rapid and regular heartbeat, typically between 250 and 350 beats per minute. Atrial flutter can cause symptoms such as palpitations, shortness of breath, fatigue, and dizziness.

Cavotricuspid isthmus (CTI) ablation is a medical procedure used to treat atrial flutter. The procedure involves creating a line of lesions (small scars) in a specific area of heart tissue, called the cavotricuspid isthmus. This line of scar blocks the abnormal electrical signals that cause atrial flutter, restoring the heart's normal rhythm.

During the procedure, a doctor uses specialized tools to guide thin, flexible tubes called catheters through the veins in the groin or neck and into the heart. The catheters are equipped with electrodes that can deliver radiofrequency energy to create the lesions. This process is called radiofrequency ablation.

After the procedure, the patient will usually stay in the hospital overnight for monitoring. Recovery time varies, but most people can resume their normal activities within a few days to a week.
